It's easier when you can attach a backtest to help debug (with the offending line commented out so the algo can finish a backtest).

I copied your code into the IDE and fixed it, take a look at the backtest below. The problem is you were comparing a price_history of 15 values to a single value of current_price. Instead, you need to compare one value to one value. I took the mean of the 15 day period to get a single result, and now the comparison runs. (see lines 16, 19). Cheers.
