very profitable, Please Help to find the problem of this AFL exploration and scanner code

[makhlaghi]

Dear Sir, Madam,
I wrote this AFL to find the trading pair in the spot market based on the MA of ADX of Vortex,
The indicator works well and shows visually what I want, but when I do analysis in AMIbroker.
the columns for the data are empty (exploration) and so no buy/sell signal (scanner).
what is the problem? please help

thanks in advance.
