Hi Grahal, out of curiosity I tried this by knocking up a random system that does a long/short reversal and didn’t get the result you are seeing. Results with spread of zero at 1 per contract were £6.71 per trade and results after with spread of 5 were £1.71. If you look in the orders list you will be able to see the prices that the trades were taken at and see the price difference between 2 trades and compare that with the results for the other spread setting. For my test it confirmed the spread was the expected 5.
