Machine Learning: kNN-based Strategy (update) 

Euro Fx/U.S. DollarFXCM

Descrizione

kNN-based Strategy (FX and Crypto)

Description:

This update to the popular kNN-based strategy features:
improvements in the business logic,
an adjustible k value for the kNN model,
one more feature (MOM),
a streamlined signal filter and
some other minor fixes.

Now this script works in all timeframes !

I intentionally decided to publish this script separately
in order for the users to see the differences.

Note di rilascio

Major fix: added scaling function for the mom feature. Mom requires scaling to the range of [0,...,100].

Why is this not drawing the last few indicators? For me, it seems to not draw the indicators in realtime, as if it cuts off the last few predictions.

@bluiska, i second this. @capissimo do we need to wait for a few close candles for it to calculate or is there something wrong?

First of all thanks for that great script and the awesome content you are producing for this community!

I would like to ask if this updated version is still repainting?
capissimo
@walfgott, unfortunately, yes. Hopefully, this community will find the proper way.

Would you please help.

Thanks.

does exist a solution to avoid repainting for this study ?

Perhaps you should turn it into a strategy and wait for the signal to be triggered on the bar close after the signal condition has been met. On the exits then you could use a strategy.exit to exit in that precise moment instead. but these are just my 2cents.

@Minimal_Est, I prefer not to and leave it to the users. You propose to use a black box magic.

@capissimo, black box magic ?
