Coding buy/stop orders above or below the price but only for a limited time

// Conditions to enter long positions
indicator1 = Average[12](close)
indicator2 = Average[22](close)
level1 = open + (10*pipsize)
c1 = (indicator1 CROSSES OVER indicator2)
IF c1 THEN
BUY 1 CONTRACT AT level1 LIMIT
ENDIF

// Conditions to exit long positions
indicator3 = Average[9](close)
indicator4 = Average[20](close)
c2 = (indicator3 CROSSES UNDER indicator4)
IF c2 THEN
SELL AT MARKET
ENDIF

// Conditions to enter short positions
indicator5 = Average[12](close)
indicator6 = Average[22](close)
level2 = open - (10*pipsize)
c3 = (indicator5 CROSSES UNDER indicator6)
IF c3 THEN
SELLSHORT 1 CONTRACT AT level2 LIMIT
ENDIF

// Conditions to exit short positions
indicator7 = Average[9](close)
indicator8 = Average[20](close)
c4 = (indicator7 CROSSES OVER indicator8)

IF c4 THEN
EXITSHORT AT MARKET
ENDIF

I am trying to create some coding for what I believe should be a simple task but I just can not get my coding head around it. Would really appreciate some help.

This is based on 4hr charts. I have a simple moving average crossover which I wish to trigger a buy order at a price 10 PIPS BELOW the trade price at the point of the crossover. If the price does not drop to that price within the next 2 bars/candles, then I wish to cancel the order.

Likewise in reverse for a crossover triggering a sell order at a price 10 PIPS ABOVE the trade price. Also to be cancelled if price does not rise to that level within next 2 bars/candles.

I have read the programming guide and done many forum searches on this, but still can’t find the solution. The coding shown illustrates how far I have got so far.

Many thanks
