I get the same backtest results as you with a spread of 1, you have either not applied your optimisation parameters and saved them or using different backtest settings as your optimisation backtest settings, do the following.
- optimise your cBot over a set start and end date with the backtest settings you wish to use with a spread of 1.
- select the best pass and apply the settings, you can also save them and load again.
- open the backtest application, set the same start and end dates, and set the same backtest settings you used with the optimisation.
- run the backtest, the results should be identical.
You can also load the saved parameters into a new cbot instance.
if the results are not identical, contact spotware support as there will be an issue with the trading platform.
