Can I get zero spread with QC ?

I am a binary options trader and I need to backtest my strategies, which requires zero spread.

In binary, there is one price only.

E.g. I open trade at 1.23400 - 1.23400 and in 30 minutes I close it at 1.23401 - 1.23401

The price has risen (no matter by how much), so a binary option would win and make me money.

However, with 1 pipette spread (the minimum I can get with MetaTrader backtester) the trade is not counted as a winning trade.
