okay, i'm relatively new to strategy testing in TS 2000i so there may be an obvious answer to my question.... here is the deal: i've added a percent based trailing stop to my entries (didn't code it myself - it was included with the software). The trailing stop works great on historical data but when i run it live (through esignal) the trailing stop triggers few seconds after the entry at around break even... So for the day my results are always BE till about 5 minutes after the market closes when the trailing stop adjusts itself to where it should have been in the first place showing me a nice profit... So i'm not sure what i'm missing here... Like i said, i'm relatively new to this and would appreciate any help. thanks a lot.
