This is very basic:
DEFPARAM CumulateOrders = false
MinLookBack = 2 //2 crossing must have occured at least these bars before PullBack
MaxLookBack = 17 //17 crossing must have occured at most these bars before PullBack
MA50 = average [ 50 ,1 ] (close )//50,1
x = close crosses over ma50
IF x OR (close > MA50 AND low < MA50) THEN //when a pullback occurs...
IF summation [ MinLookBack] (x[ 1 ] ) = 0 THEN
IF summation [ MaxLookBack] (x[ MinLookBack + 1 ] ) AND Not OnMarket AND close > open THEN
BUY 1 CONTRACT AT MARKET
SET STOP pLOSS 50 //50
SET TARGET pPROFIT 300 //300
ENDIF
ENDIF
ENDIF
When it detects a crossover it is interpreted as a crossover due to pullback if there has been a previous crossover AT LEAST min candles before and AT MOST max candles before.
