Backtest result keep changing


hello all
I Am trading in 15 Minutes Candle Stick in cash segment for waiting period of 2 hours for Stop Loss or target (Exit after 2 Hour from buy or sell condition). In the scan result there are 3 to 7 signal for buy or sell . I select only one signal from, scan result, & trade within that period I did not take in other position, but after completion of that present day I see the back test result shows the another script which I did not trade. So I need to trade on the same which shows the back test result shows for present day.

Will you please guide me how to write code in AFL or what is the setting of back testing.
Waiting for your positive response.

Please explain how to trade as per back test result for present day
