my strategy is simple, just check if the 30min bar closing price is above or below both the short and long MA and enter trade accordingly. After the backtest I realize there are two problem:

1) From the backtest log, I see that the trades are not entered on 00min or 30min. So I wonder I have set this up correctly.

2) The backtest stopped since Nov 7, but my backtest test is setup to run to current time.

Thanks everyone for your help.
