Understanding How Your Orders Actually Get Filled
You Click "Buy." What Actually Happens Next?
Most traders see a chart and think that's the market.
But the chart is just the surface. Beneath it lies a complex ecosystem of orders, matching engines, market makers, and execution venues.
Understanding market microstructure won't make you a better chart reader. But it will make you a better trader.
What Is Market Microstructure?
Definition:
Market microstructure is the study of how markets operate at the mechanical level how orders are placed, matched, and executed.
Why It Matters:
Explains why prices move the way they do
Reveals hidden costs of trading
Helps optimize execution
Exposes market manipulation tactics
The Order Book
What It Is:
A real-time list of all pending buy and sell orders at different price levels.
Structure:
ASKS (Sellers)
$50.05 | 500 shares
$50.04 | 1,200 shares
$50.03 | 800 shares
$50.02 | 2,000 shares ← Best Ask (Lowest sell price)
$50.00 | 1,500 shares ← Best Bid (Highest buy price)
$49.99 | 3,000 shares
$49.98 | 1,000 shares
$49.97 | 2,500 shares
BIDS (Buyers)
Key Terms:
Bid: Highest price buyers are willing to pay
Ask: Lowest price sellers are willing to accept
Spread: Difference between bid and ask
Depth: Total orders at each price level
How Orders Get Matched
The Matching Engine:
When you place an order, it goes to a matching engine that pairs buyers with sellers.
Priority Rules:
Price Priority: Better prices get filled first
Time Priority: At same price, earlier orders fill first
Example:
You place market buy for 100 shares.
Best ask is $50.02 with 2,000 shares.
You get filled at $50.02 (takes liquidity from the ask).
Types of Market Participants
1. Retail Traders
Individual traders like you
Typically small order sizes
Often use market orders
Price takers (accept current prices)
2. Institutional Traders
Hedge funds, mutual funds, pension funds
Large order sizes
Use algorithms to minimize impact
Can be price makers or takers
3. Market Makers
Provide liquidity by quoting both bid and ask
Profit from the spread
Required to maintain orderly markets
Use sophisticated algorithms
4. High-Frequency Traders (HFT)
Trade in milliseconds
Exploit tiny price discrepancies
Provide liquidity (sometimes)
Can front-run slower orders
The Spread and Its Implications
What the Spread Represents:
Cost of immediate execution
Market maker's compensation
Liquidity indicator
Spread Dynamics:
Tight spread: High liquidity, low cost to trade
Wide spread: Low liquidity, high cost to trade
Example:
Bid: $50.00, Ask: $50.02
Spread: $0.02 (0.04%)
If you buy at ask and immediately sell at bid, you lose $0.02/share
Implication:
Every round-trip trade costs you at least the spread. This is why overtrading is expensive.
Price Discovery
How Prices Move:
Prices move when there's an imbalance between buying and selling pressure.
Scenario 1: More Buyers
Buyers consume ask liquidity
Price moves up to find more sellers
New equilibrium at higher price
Scenario 2: More Sellers
Sellers consume bid liquidity
Price moves down to find more buyers
New equilibrium at lower price
Key Insight:
Price doesn't move because of "sentiment." It moves because orders hit the book and consume liquidity.
How AI Uses Microstructure
1. Order Flow Analysis
AI tracks:
Aggressive buying vs selling
Large orders hitting the book
Imbalances in bid/ask depth
2. Spread Prediction
AI predicts:
When spreads will widen (reduce size)
When spreads will tighten (better execution)
3. Optimal Execution
AI determines:
Best time to execute
Optimal order size
Which venue to use
4. Market Making
AI market makers:
Quote bid and ask continuously
Adjust quotes based on inventory
Manage risk in real-time
Microstructure Concepts Every Trader Should Know
1. Slippage
The difference between expected price and actual fill price.
Causes:
Market orders in fast markets
Large orders relative to liquidity
Wide spreads
Mitigation:
Use limit orders
Trade liquid assets
Avoid trading during low liquidity periods
2. Market Impact
How your order affects the price.
Reality:
Large orders move prices against you.
Buying pushes price up
Selling pushes price down
Mitigation:
Break large orders into smaller pieces
Use algorithms (TWAP, VWAP)
Trade over time, not all at once
3. Hidden Liquidity
Orders that don't appear in the visible order book.
Types:
Iceberg orders (only show portion)
Dark pools (private exchanges)
Hidden orders
Implication:
The visible order book doesn't show all available liquidity.
4. Queue Position
Your place in line at a price level.
Why It Matters:
If you're 1,000th in queue at $50.00, you won't get filled until 999 orders ahead of you fill.
Implication:
Limit orders at popular prices may not fill even if price touches your level.
Practical Microstructure Applications
Application 1: Reading Order Flow
Watch for:
Large orders hitting bid/ask
Absorption (price holds despite volume)
Exhaustion (volume without price movement)
Application 2: Timing Entries
Enter when:
Spread is tight
Liquidity is high
Order flow supports your direction
Application 3: Avoiding Bad Fills
Avoid:
Market orders in illiquid assets
Trading during news (spreads widen)
Large orders relative to average volume
Application 4: Understanding Wicks
Wicks often represent:
Liquidity being taken
Stop hunts
Temporary imbalances
Microstructure Red Flags
Widening Spreads Indicates decreasing liquidity, higher trading costs.
Thinning Order Book Less depth = more volatile price moves.
Unusual Order Patterns Spoofing, layering, or manipulation attempts.
Delayed Fills Your orders taking longer to fill than usual.
Key Takeaways
The order book is where price discovery actually happens
Spread represents the cost of immediate execution
Your orders have market impact larger orders move prices against you
AI can analyze order flow and optimize execution
Understanding microstructure helps you get better fills and avoid hidden costs

Execution
Perfect Execution - Waiting for Confirmation Saves AccounsKey levels attract attention, but attention alone rarely produces good trades. A level gains meaning only when price shows how it behaves around it. Many traders understand where important levels are, yet still lose money because they enter too early, assume a breakout will continue, or anticipate a reversal before the market confirms it.
Patience at these levels is what separates disciplined execution from unnecessary losses.
A key level acts like a pressure point. Liquidity gathers above highs, below lows, and around clear support or resistance.
When price approaches these zones, it does not move cleanly. It probes, sweeps, hesitates, or accelerates depending on who holds control. Entering at the first touch is often an emotional decision disguised as confidence. Entering after confirmation is a structured decision grounded in evidence.
Confirmation begins with a reaction. A legitimate bounce or rejection has intent behind it. You will see displacement, cleaner momentum, or a defined shift in micro-structure. A candle wick alone is not confirmation.
A single green or red candle is not confirmation. Confirmation comes when the market shows that a level is respected or rejected with conviction, as several conditions align.
One of the clearest signs of confirmation is the break of micro-structure after the level is touched. If price sweeps a low and then breaks a minor high, the narrative changes. The same applies to resistance: a sweep followed by a failed attempt to push lower is evidence of buyers stepping in.
This structural shift shows that the reaction is more than a random bounce.
Another layer of confirmation is the retest. Strong moves often return to the level they broke to validate participation.
Traders who enter before this retest expose themselves to unnecessary volatility. Traders who wait allow the market to prove that the move is real, not a trap.
The retest reduces risk naturally and improves the reward-to-risk ratio without changing the strategy itself.
Patience does not slow you down. It filters out trades that look attractive but lack substance. Key levels attract liquidity, manipulation, and emotional behaviour.
Waiting for confirmation keeps you grounded when the market is trying to provoke a reaction. It prevents you from turning strong levels into weak trades through premature entries.
The goal is not to catch the exact top or bottom of a move. The goal is to participate in moves that show clear strength and clear intent.
When you treat key levels as decision points rather than entry signals, your trading becomes structured, disciplined, and far more consistent. Patience is not passive. It is an active skill that protects your account and elevates your execution.
BTCUSD | London Session | Bullish Structure BalanceThe monthly bullish structure balance has now been filled, and the higher-timeframe map remains intact.
BTC continues to rotate inside a bullish range and is still positioned in the discount zone.
Range boundaries:
• Range low (invalidation): 78.167
• Range high (continuation): 123.231
As long as price holds above the range low, the bullish bias stands.
- Market Structure Mapping (MSM) — Current View
The structural picture is straightforward:
BTC is holding a clean range.
There is no breakdown. No structural shift.
The architecture is stable.
Cross-market structure adds context:
• The U.S. dollar sits directly on a major volume node.
If the dollar pushes higher from here, risk assets usually feel it.
If the dollar softens, crypto keeps its bullish rotation.
• FX majors recently cleared liquidity lows, resetting the structural map.
• Crypto majors remain balanced with no directional damage.
This is a classic data-waiting phase.
The structure is already drawn. The market is waiting for a catalyst to decide the next expansion path.
- Precision Execution Modeling (PEM) — Guidance for Volatile News Days
When heavy data is on the calendar, PEM shifts the playbook:
• Do not react to the first spike.
The wick is emotion. The candle close is intent.
• Step back to higher timeframes.
4H and 1D candles filter out noise and reveal real direction.
• Expect wicks to violate levels without changing structure.
Large funds do not trigger algorithms on a random spike; they react to confirmed structure.
• Protect capital until the market shows its hand.
In fast conditions, patience is a position.

If you need excitement, watch Netflix. If you need results, wait for the candle close.

Institutional Logic. Modern Technology. Real Freedom.
Gold execution psychology - why do your trades fail on XAUUSD?🎯 You Knew the Zone but the trade failed.
Execution psychology for Gold traders who are tired of guessing.
You marked the zone.
You waited for price to tap into it.
Maybe you even caught a reaction — but the trade failed anyway.
Not because the zone was wrong.
Because the execution broke down.
🧠 1. The Problem Isn’t the Zone. It’s the Trader.
There are two valid entry styles:
🔹 Bounce Entry
→ Enter on first touch of the zone
→ Works best when:
• Structure supports your bias
• Liquidity has been swept
• You're using a refined zone (OB, FVG, confluence)
→ SL must sit outside the zone — not inside it
→ Fast entries, fast rejections — but high responsibility, not for beginners.
🔹 Confirmation Entry
→ Wait for CHoCH or BOS on M5/M15
→ Enter on the retest
→ Cleaner invalidation, but slower execution
→ Less drawdown, but requires patience
⚔ 2. Your Stop Loss Was a Suggestion, Not a Standard
Gold isn’t EURUSD.
This pair moves 100–300 pips in minutes — and it will wipe out shallow SLs for fun.
Your SL must sit:
• Below the OB (not inside it)
• Outside the liquidity sweep
• Beyond the structural invalidation point
💰 Lot Size Must Match Your SL — Not Your Ego
We don’t increase lot size because we hope it will go perfect.
We always trade small — because Gold doesn’t need size to give payout.
The wider the SL, the smaller the lot.
That’s how you control risk and let price move.
We don’t chase leverage.
We prioritize precision, patience, and profit.
📉 3. After One Loss, You Lost the Plot
One trade didn’t go your way — now you’re flipping bias, skipping rules, and forcing setups.
That’s not trading. That’s emotional spending.
Real traders analyze the loss.
They re-read the setup.
They take the next trade — only if structure allows, even skip trading to the next day.
✅ So How Do You Fix It?
1. Define your entry style
2. Keep lot size small — even with 100 pip stops
3. Move SL to BE when appropriate
4. Walk away after 2 losses.
Accept that one good trade is better than 5 emotional entries, clear mind -cleaner executions.

550+ Points Secured on MNQ | Bullish FVG + Gap Fill PrecisionIn today’s trade, we captured over 550 points on MNQ, banking a solid $288 profit on one clean, high-probability setup.
Here’s the breakdown:
Sunday’s open left a gap above, creating a clear target for buy-side liquidity.
During Asia, price dipped into a validated Daily Bullish FVG, which had previously been traded through and reclaimed — a powerful sign of support.
As price retraced into the 30m FVG and approached its high, I entered at 7AM, aiming for the equal highs above.
Although we exited slightly early before the 10am open push, price ultimately fulfilled the full TP target, confirming the strength of the setup.
🎯 Bonus insight: As mentioned in the video, re-entry at the 50% of the 30m FVG was also valid — and it could’ve netted another 600+ points. That’s how powerful these FVG structures are when aligned with narrative and timing.
Watch the full video to see the exact entry logic, TP strategy, and lessons learned.

MNQ Buy Idea 5.29.25 (Part 2)Continuation of the first video entry of this trade.
We were aiming for $200 in profits today but failed to get that, ending with $61 in profits. I don't think we will be entering another trade due to the time and also that I want to focus on reading my book "The Trading Game" by Ryan Jones.
If you guys found this insightful give it a 🚀, it helps me see that you guys learned something from watching this and motivates me to post more.
Drop your comments down below, do you think MNQ is bullish or bearish? What prices do you see MNQ reaching?
Quick Win on MNQ with Over $250 Profit — Here’s the Setup!Today’s trade was a perfect execution using an inverse fair value gap. I spotted a bearish fair value gap that had been disrespected, and instead of fading it, I flipped the bias and used it as an inverse gap, anticipating price would not trade under it. With my stop just below, I targeted the buy-side liquidity near the London kill zone highs.
The result? A smooth ride to over 300 points and a $250+ profit in a single entry, reaching target with precision. This is how it’s done when you combine technical setups with market context. Keep your risk low, target the right liquidity zones, and let the market work for you.

10 AM Trade – Entry After Buy-Side Liquidity ManipulationAfter the 10 AM candle formed, price quickly expanded higher, as we had anticipated, taking out the buy-side liquidity before tapping into a new week opening gap low. Once this manipulation played out, I observed the price action on smaller timeframes, particularly the 1-minute chart, where we saw a bullish break for value gaps. I used this as an inverse setup to enter on the third or fourth candle.
The trade eventually played out, moving lower as expected, setting the stage for further price action that I’ll explain in more detail in the upcoming videos.
Trade Overview:
Entry: After the 10 AM candle, based on a break of a bullish FVGs on the 1-minute
Bias: Anticipating buy-side liquidity manipulation and a move toward lower prices
Execution: Entered on the third or fourth candle, holding for a continuation lower.
MNQ 5.20.25 Trade Idea (2)Execution, Risk management and Profit taking shown live in the next 3 posts I am about to share with you guys.
I wanted to use that 4H 10am Low as an entry and we caught it. Now we are watching to see if that was just a manipulation to trade into that bearish FVG I outlined near that Buyside liquidity area we were targetting.
Closing the day out with $110 in profits, Which you will see on Video #3
NQ Live Trade Idea & ExecutionWhat's Up everyone! I know I have been MIA, but that's because I have been focusing on my learning and I realized that content creation takes away a lot of the time I have for that. Once in a while when I see something beautiful I will share it with you guys here. This trade was the perfect example of a beautiful trade idea and management. We were able to profit over $3,000
on a couple trades taken on NQ and this is 2 contracts that I had running, one was taken profit at the highs while the other was stopped out in profits. As you can see they are taking quite a while to go for those Asian highs so they are potentially building liquidity above I believe. We will have to wait and see what the market presents us.
We utilized a 15M Bullish FVG turned inverse as an entry on an earlier trade, then the NWOG 25% PDA level as a second entry and then again inside the NWOG another entry inside of a Bullish FVG turned IFVG as well which lined up perfectly with 50% of the NWOG as well.
These trades were all profitable and netted me over $3000 all together.

Fair Value Gap’s.
• 5,740 – 5,830 on the daily
• 6,038 – 5,934 on the daily, filled in by last candle
• 5,979 – 6,016 on the 2H, (23 Dec 15.30 – 24 Dec 11.30)

• 6,037 – 6,063 on the 1H, (17 Dec 15.30 – 18 Dec 11.30)
• 5,892 – 5,840 on the 30M (19 dec 15.30 – 20 Dec 09.30)
Liquidity pool:
• 5,700
• 5,854 (Got hit at 09.30 and Bullishly swept from 09.50 ending in a Premium short with the use of Equilibrium at 12.00)
• 6,102
I think we are going to se it draw back in to the FVG that the last three 2H candles created before then testing the Order Block at 6,037 – 6,063 and procced to hunt the liquidity laying at 6,103 since it’s on a bullish rally on the daily since 20 Dec after hitting Liquidity laying there.
Before dipping all the way down to the FVG at 5,740 – 5,830.
And I think it will go on to the Premium buy side since the market would probably want to hit the Liquidity laying at 5,700.
Though I really doubt it is going to hit that since we are in an weekly uptrend.
From the previous reactions of all the building block I showed it seems it will still follow the same pattern if not any news shows up, I have showed prices reacting of previously named building blocks and then proceeded to predict it next moves based on that the market will continue that pattern.
Ideally the best entry for a short would in my opinion be at 6,102 and above after seeing a break of structure to the downside at the 15M chart.
I am pretty new to this so would love any feedback. You don’t agree with the analysis? Then please comment why so I could see you’re resoning.
Trading is execution - USD/JPY Live trading exampleThis is a short mentoring/educational session.
The USD/JPY is the pair we are trading this evening, I analyse this based on the mtf wave structure.
I explained the importance of the secondary trend, as a determinant tool or information for what may happen in the future.
I also shared one of my waves of success strategy using the DMI and the VMP for trade execution.
Finally, after taking the trade, I explained late Mark Douglas probabilistic principles which acts as a solid foundation of our behaviour and interaction with the market.

i see this as a good risk to take given the confluences of the higher time frame not breaking that high, so their is a likelihood of price moving back to the upside. given the structure and the price action on the higher time frame i can see a last leg forming to an ascending structure. an entry can be made out on the 4H in the form of a larger flag, its just a matter of pulling that trigger at the right moment for me now. a risk of 1% will be executed if the criteria is met to my trading plan, if im stopped out im happy with the position in this frame of mind - given the potential this move has to the upside.
