Python dev trying to get started with thinkscript

Traders, hello...

I have a TOS account, and I thought I'd deviate from my python work, to write some custom scan criteria within the platform. I've hit a bit of a wall; after a day of searching and reading the, uh, 'docs' I'm no closer to a solution. My question is:

In the scanner condition environment (99% of web examples seem to work with strategies), how does one refer to, or loop over (whatever the best way is) past bars?

I'm looking for a 50sma > 200sma over the past 100 days, and no closes below the 200sma over the same lookback. Should be pretty simple. I've tried 'fold' to no avail.. it seems to be a plotting- related function.

Can someone get me started in the right direction? It'd be huge. Thanks!

def avg50 = average(close,50);
def avg200 = average(close,200);
plot x = sum(close< avg200,100)==0 and sum(avg50 > avg200,100)==100;

it will check if close is equal to or greater than avg 200 for 100 days and if avg50 is greater than avg200 for 100 days

That is fantastic. Thank you so much...
