Well, I would appreciate any help about this, please!. I have a few automated systems on Tradestation designed for 2 min charts. I think that my backtest isnÂ´t correct because: how does the program knows what is exactly the price when the system gives a signal to enter at market?. I mean, in real time you see the information comming tick by tick, but in a 2 min chart there is no such precission, right? How can you solve this on Tradestation? any suggestion about any other platform that could use tick by tick information on backtesting X min charts? Please help! Many thanks in advance.
