Hi, That is NOT a solution. The delay is not a constant. The delay necessary before a Zig signal becomes valid will vary at each point depending on the volatility of the market. It might be as few as a single bar, or it may take years.
The key is that you must verify that the price has actually moved the desired amount (i.e. the zig percent) before you can recognize the last Zig signal as valid. See this example in the library. http://www.amibroker.com/members/library/detail.php?id=353 If charting the above, change NULL from the following lines to be 0 instead. PivotLow = Ref(IIf(Ref(ROC(ZZ,1),-1) < 0 AND ROC(ZZ,1) > 0, 1, Null),1); PivotHigh = Ref(IIf(Ref(ROC(ZZ,1),-1) > 0 AND ROC(ZZ,1) < 0, 1, Null),1); Mike --- In [email protected], "sebastiandanconia" <sebastiandanco...@...> wrote: > > What I did to "solve" the problem of looking into the future with Zig-Zag was > to just add in a trade delay. > > Example: Tomasz has written a double-top pattern detector here... > http://www.amibroker.com/library/detail.php?id=19&hilite=PEAK > > ...and in the line "buy = doubletop;" I modified it to say > "buy=ref(doubletop,-5);". > > Zig-Zag doesn't "know" that a peak was made until a few bars go by after the > suspected "peak", so you add that number of days to the signal generated by > Zig-Zag.
