Spotting where the buy stops and sell stops (which the institutional traders would look for and eventually consume it) is not that difficult. All you need is to think "when I was a newbie trader, where would I put my stops based on xyz method"
The most common stop losses that is easy to spot are ones for reversal traders (using reversal candlestick pattern such as the bearish engulfing candle for a short signal) and retracement traders (and MA crossover traders)
You can refer to the chart what I am talking about.
Once you determine the potential stops, then that becomes your own discovered liquidity pool. It will come very handy for your own entry points, bias setting or simply knowing which levels to avoid to put your stops. Remember, institutional traders have BIG positions to make and with big positions you need liquidity so there will be no slippage when they make their market order
(i.e Bank Trader in Canada wants to buy 500 million units AUD at 0.90600 but not enough supply/sellers at that price, so to avoid being filled at much more expensive price (slippage), then he wait and/or manipulate the price where there are enough sellers for him to buy the AUD that is at a better price than 0.90600.
Liquidity Pool is the area where the Bank Trader in Canada would look to buy the AUD and where that liquidity pool would be? Where there are a lot of stops. 0.89800 resides a lot of stops that would be enough for the 500 million order to be filled without slippage (This is just an oversimplification, sometimes Banks would split their orders)
Using my own personal market navigational method, I draw Friday High and Low, and see where the price would close above/below.
If price breaks above Friday low, I would see if it could breaks above the blue line where the bank would take out all the stops around 0.90400-0.90800 (the higher the better) there and then perhaps push the price down after that.
If price breaks below Friday low, I would see if it could break the stops around 0.89800-0.89600 (the deeper the better) and then I would be looking for a bullish trigger to long AUDCAD
