can you help me, i want to do a setup like this:

buy rsi (2) below 5

sell when the average of 13 cross the rsi 2

hope this will work. assuming that average 13 means rsi(2) 13 period average. If u mean to price then just replace rsi(2) to close.

Media7 = MA(Close, 7);
Media13 = MA(Close, 13);
mEDIA20 = MA(Close, 20);
 
 
Buy =  RSI(2) < 5;
/*Sell = IIf(MEDIA20 > Ref(MEDIA20, -1), Cross(Close, MEDIA13), Cross(Close, MEDIA7));*/
sell=cross(ma(rsi(2),13),rsi(2);
 
// trade on next bar open
SetTradeDelays( 0, 0, 0, 0 );
BuyPrice = SellPrice = Close;
 
// trade size: 100% of current portfolio equity
SetPositionSize( 100, spsPercentOfEquity );
