newdigital,

I tried to use the Expert Advisor Builder, after save it and do the strategy tester
an error occured
'2008.08.07 15:48:33 TestGenerator: unmatched data error (low value 1.5458 at 2008.08.05 17:45 is not reached from the least timeframe, low price 1.5464 mismatches)'
It's a simple logic EMA 12 cross EMA 21
What cause an error?
TIA
Zen
