Hi,
I rewrote the Signals example script. Improvements are the following:
It does the same thing, but a lot faster…
You can get it here: GitHub - nemethpeti/Signals
Note, that just by changeing the seed of the boosted tree changes the resulting mean corr and sharpe. You can ignore that, this just something to start with.
Have fun!
This looks awesome, should definitely become the new example script
So good, thank you! Especially love the download of delta only!
Looks like RSI10*** was hard coded in a number of places, so if one changes the interval the code breaks? I’ve tried to change it using f-strings (like below) but still can’t get the code to run completely:
f'RSI{interval}_quantile'
Yup 
That’s exacly what I’m working on now. Trying to add more indicators with more timeframes…
If you have a cleaner version, please post it here!
Great! This is what I have so far. Not the best (I’m a poor coder). If I knew how to use git and GitHub properly I would do a pull request there.

I’m glad you didn’t do a pull request, because I have no idea, how to handle it 
@joakim,
I got the error below when trying to submit signals data
" Not enough stocks submitted, must include at least 10 predictions for the tickers in the signals stock market universe for the current live time period and there were only 0
@nyuton
I keep on getting Number of live tickers to submit: 0
