Waiting for some bars before entry

I want to create a code for scaling in if the same conditions are met 3 times.

i.e., if there is a buy signal and again BUY signal conditions are met before SELL (LongExit) condition, then the system could take the BUY signals upto 3 times and then exit all at the SELL condition.
i have a code which works like this but it generates 3 signals on 3 continuous candles which leads to losses. have attached image for clarity.

now i need to create a code which waits for a certain number of candles before scaling in.

somebody please help!

I am not sure to understand you correctly. I guess you want to scale-in every time you get a Buy signal, up to 3 times. And sell your whole position when you get a Sell signal. But you also want to wait for n bars after last Buy signal before buying more. In that case,
let's say your long signals are given by a BuySignal variable and your sell signals by a SellSignal.

Code

n = Param("Delay to scale in", 5, 1, 20);
maxScaleIn = Param("Max scale in", 3, 1, 10);

Delay = BarsSince(BuySignal); // Bars since last Buy signal
Pos = Flip(BuySignal, SellSignal); // position in the market

BuyFirst = (Pos > 0) AND (Ref(Pos, -1) <= 0); // first buy signal, no delay
BuyMore = BuySignal AND (Delay >= n); // next signals, n bars delay
BuyNoMore = (Sum(BuyMore, BarsSince(BuyFirst)) + 1) >= maxScaleIn;
Buy = BuyFirst OR BuyMore AND (NOT BuyNoMore);

Similarly for the short side. I haven't check code but it should be ok. Have fun.

Alligator,

thanks a lot for your reply. the code is not working though. it is generating only one buy signal instead of three. i will see what can be done now. thanks again.

I don't have time to check, but there's at least on error preventing more than 1 buy. Replace Delay by:

Code

Delay = Ref(BarsSince(BuySignal), -1) + 1;
