AUDUSD 15 - QF Demo Trade

1.- Price hit Scan Entry line
2.- Price went through Bollinger Bands
3- RSI below 30
I closed the trade before hitting the 10 pips gain and the 15% scan success level becuase at some point the price pulled back 3 pips. Was I supposed to do that, or should I had just let it run until it either hit the +10pips target or the -10pips StopLoss?
This trade was this morning, but I am posting it until now because I am not allowed to use facebook at my workplace (gosh! my 6 to 6 job is killing me)
