Hello! Everyone...
I am using the trail version of Amibroker Standard 32 Bit .
Q:- Why for some Trading System the backtester gives buy and sell signal only for last certain percentage of data say(15% Approx) and for rest prior data it generates only sell signal. And i have checked the conditions of buy that are met even in the prior data also and its happening for every ticker on which i perform backtest operation. Whether i restart Amibroker or reinstall it results are same. Its happening only for that particular trading System for other trading systems there is no problem. Here's the screen shots.
Here in 1st shot u see backtest operation was performed on all Quotes (since 2014) loading MY SYSTEM 1 Trading System (Circled on right top corner ) in which problem is caused. Here it generated buy signal from 03-07-2018 (Circled on left side). Even buy conditions are met in prior data also but there only sell signals are given i have checked in trade reports generated by Scan.
Here's the second shot
Here in 2nd shot with different trading system MY SYSTEM 2 (Circled on top right Corner) and Range with all quotes there is no issue in backtest operation proper buy and sell signals are given on whole data (since 2014 Circled on left side).
If anyone already faced this problem and knows the solution to this please help me.
Thank you.
