[amibroker] Q regarding removing succeeding signals from HighestSince or LowestSince

["janhausd" <janhaus@xxxxxxxxx>]

Hi,

I did some searching in the posts, and it looks like many people have
asked for methods to remove the extraneous signals from HighestSince
or LowestSince so that the function can return the very first signal
and not the ones which appear afterwards.

I've tried copying the code from these two posts, using loops or loops
+ global vars, or some combination of ExRem, or Flip or ExRemSpan but
I have not yet gotten it working:

Is there a simple way to accomplish this? Otherwise, the trailing
stops don't work correctly since HighestSince is reset with each
succeeding Buy signal and vice versa for LowestSince. The below is the
code I'm looking to fix:

---
Buy = Signal1 & Signal2;
Short = Signal1Rev & Signal2Rev;
Buy = Ref(Buy,-1);
Short = Ref(Short,-1);
BuyPrice = O;
ShortPrice = O;
SetTradeDelays(0,0,0,0);

sellstopline = HighestSince( Buy, High ) * STrailingStopPct;
BuyBarsSince = BarsSince(Buy == 1);
sellprofitline = Ref(BuyPrice, -BuyBarsSince) * SProfitStopPct;
sellex = sellstopline > P;
sellex2 = P > sellprofitline;
Sell= IIf(sellex,4,(IIf((sellex2),3,0)));
SellPrice = O;

coverstopline = LowestSince( Short, Low ) * BTrailingStopPct;
ShortBarsSince = BarsSince(Short == 1);
coverprofitline = Ref(ShortPrice, -ShortBarsSince) * BProfitStopPct;
buyex = P > coverstopline;
buyex2 = coverprofitline > P;
Cover= IIf(buyex==1, 4, (IIf((buyex2),3,0)));
CoverPrice = O;
Equity(1,0);
