1-first with hst file do backtest fxcore100 and fx88 or flex
2-then remove .hst files
3-then get backtest from fxcore100 and fx88
and compare result
you will see result of fxcore100 not changed
and fx88 can't open any trades

back test use .fxt file in tester folder
.hst is chart data

so simple delete .hst 240 and recheck backtest
they can't open any trade

back test use .fxt file in tester folder
