Simulated slippage in pips/ticks – it will add the specified number of pips/ticks to the opening and closing price.
I was trying to verify my suspicions, that's when I noticed all zero's in the slippage column.
As a side note, please clarify is the slippage setting of 4 supposed to add 4 to the open and also add 4 to the close? Or would 4 be added total round trip such as 2 to open and 2 to close?
the slippage column is inteded for Tradestation/Multicharts engine. It shows the total trade slippage in dollars.
When you backtest with TS/MC engine, the open a close price is not modified and the slippage is applied to the trade PL.
For MT4/MT5 engines the slippage in pips is applied directly to the opening and closing prices of orders.
If you set slippage to 1 pip, the trade will be opened and closed for 1 pip worse price. In tradelist slippage column will be zeros.
Best regards,
