Hi all,
I've been meaning to play around with an RSI algo attempt posted a while back: https://www.quantopian.com/posts/rsi-attempt-general-questions-and-feedback
I had to make a few changes (see source) as context/data usage became different as the platform was upgraded...but I'm still getting an error and I'm a little confused why...
Any ideas?
Thanks
Alex
Hello Alex,
I'n sure there are better solutions but you could try
log.info(str(rsi))
record(RSI=rsi)
Regards,
Peter
Alex,
The problem is that it's having problems changing your integer to a string for logging. It works if you do it explicitly. Change line 76 from
log.debug(rsi)
to
log.debug(str(rsi))
For more readable logs, I'd combine lines 75 and 76 like this:
log.debug('RSI is: ' + str(rsi))

Ah simple enough, thanks.
I didn't realize it was something that simple causing the problem... when run step by step in isolation, this line was giving me problem (basically never ending)
returns = [(preceding_prices[i-1]-preceding_prices[i]) for i in range(1,len(preceding_prices))]
but it seems to be fine now...
