Tick Backtest vs minute sampling data
13 May 2015, 00:52
Hi guys,
I wrote a small algorithm and back tested using minute bars data. Seems profitable. Then I started it in demo account and is behaving totally opposite. I decided to backtest using tick data this time and my system is not profitable.
My question is: when I simulate using tick data, the spread is present as well? On minute chart I can chose an average spread, but on tick data don't have this option
Tnx

Ticks are a bid and ask, so they include the spread.
