AR Forecast Scatterplot [SS] 

Invesco QQQ Trust, Series 1NASDAQ

Description

This is a showcase indicator of my recently released SPTS library (the partner of the SPTS indicator).

This is just to show some of the practical applications of the boring statistical functions contained within the library/SPTS indicator :-).

This is an autoregressive (AR), scatter plot forecaster. What this means is it tags a lag of 1, performs an autoregressive assessment over the desired training time, then uses what it learns over that training time to forecast the likely outcome.

Its not a machine learning (I am in the process of creating one like this, but it is taking quite some time to complete), but the model needs to learn to plan the statistical coefficients that will best mimic the current trend.

As of its current state, this actually surpassed my own expectations. I can show you some QQQ examples:

Example #1:

Prediction:



Actual:



Example #2:

Prediction:



Actual:



Pretty nuts, eh?
Statistics, I'm telling you, its the answer haha.


So how do we determine the train time?

Because this is not using machine learning to control for over/under representation of datasize (again, I am making a version that does this, but its a slow process), some quick tips at determine appropriate train time is to use the Tradingview Regression tool:



When you set the parameters to align with the current, strongest trend, it is more reliable.
You will see, that it acutally is forecasting a move back to the exact top of this trend, that is because it is using the same processes as the linear regression trend on Tradingview.

You can use a bar counter indicator (such as mine available here) to calculate the number or bars back for your model training.

You can verify that these parameters are appropriate by looking at the Model Data table (which can be toggled on and off). You want to see both a high correlation and a high R2 value.

Quick note on colour:

Green = represents the upper confidence predictions (best case scenario)
Blue = represents the most likely result
red = represents that lower confidence (not as best case scenario)

Hope you enjoy!

Safe trades everyone!

Release Notes

Added the ability to toggle between line plot and scatter plot (circles). The line plots show the timeframe marked better than the circles, but the circles look more aesthetically pleasing.

You can decide which you prefer!

Release Notes

Quick bug fix.

Release Notes

Created 1 new tool and modified some things. Here is what has been added/changed:

Added:
  • The ability to toggle off the variances and only plot the most likely results. This just makes for a cleaner chart with less to account for.

  • The ability for the indicator to plot the predicted trend, by plotting a trendline from the first forecasted result, to the last forecasted result.


Fixed:

There was an error. The statistical model parameters (correlation and R 2) should have been attached to the lag value in the forecast. I have fixed this. All this means is, if you are forecasting 14 bars into the future, the model will look to see how the ACF or autocorrelation function, performs 14 bars back. The further you attempt to forecast in the future, the less reliable the results are owning to an overall decay in autocorrelation after xyz candles.

Enjoy!

Release Notes

Quick fix

Release Notes

Updated to include an auto-trend identification. It will auto identify the best lookback length.
This can be manually over-rode in the settings.

Also added the ability to just toggle on the trendline.

Release Notes

Replaced the trendline with a Polyline.

Release Notes

Label delete fix,
Special thanks to @peacefulLizard50262!

This will now delete labels/plots on new candles.

So good with advance level, i hpe to see the next level of ML

Hii! Testing this today and really loving it! Quick question: in your examples, did you consider the trendline with the variances or just the variances? I noticed you don't have the purple line plotted in your screenshots. Thanks again for such a cool indicator!
Steversteves
@yisk4h, Thanks, I am glad you like it! :-), I have been using it quite a bit actually haha and I tend to just turn of the variances and only look at the results for shorter term stuff. For longer trajectory stuff I will look at the variances to see kind of how high and low it could go based on the current setup.
Hope this answers your question!

@Steversteves, Yeah, from what I've observed, the results are great! (Just to make sure I got it right: when you say results, you mean the purple line?) Using statistics is genius!
