Hi, newbie question here.

I know that you can have thinkscript look at bars with a negative number, for example

def a = study<study[-1]

but how does this work exactly? Isn't this looking into the future?

When programming strategies you may want to have your entry triggered on the close of the next (future) bar. However, when backtesting, it's not really a future bar because it's already in the past. It's just the next bar after your conditions for entry have been met.

Well explained, thank you
