no, you can just use daily data (open, close, high, low).
Yes the backtesting feature has some problems. I still use it and if I find something that looks good do the calculation by hand (you can do this with "offset").
Then you click on "performance" and click through.
offset = 1
Show stocks where RSI(2) is less than 1
and close is between 0.1 and 5
and close more then 5% below close 1 day ago
and average price (10) * average volume (10) > 50000
