@trash..
if u have solution of tick acktesting in amibroker then u can give a demo afl performing that function.
i contacted ami support ,they told that timeframe expand functions cannot help in implementing this. they also told that amibroker was capable of doing this but it would require lots of programming which they could'nt provide under free support..
trash, i dont know whether u are able to perform this on amibroker or not or willing to divulge that knowledge .but pls do not ask some1 to read help file ,and say its all there .
if u still can show us the way to implement this on ami,we will be highly grateful for that.otherwise its ok.
