Hi,

The Symbol.Spread does change based on live difference between symbol bid and ask price levels.

Are you using Symbol.Spread on back tester? if you are back testing and you want to use Symbol.Spread then you must use tick data for your back test not bars data.

I see! That makes sense and yes, this was during a backtest without real tick data
