In your experience using TradeStation backtesting, do you normally use slippage per trade or slippage per contract? For example, I am working on a MCL script, and I know 1 tick is equal to $1.00. So, I factor in $2.00 (2 ticks) of slippage per trade (which is just my stop loss, my entry is a limit order). However, I was wondering if it would make more sense to set slippage per contract instead of per trade? I don't think we would set $2 of slippage per contract, especially on larger orders.
Thoughts?
Can you help answer these questions from other members on NexusFi?
IMHO of course per contract and sorry, I don't understand your logic because of larger orders, you can be sure, the larger the order, the larger the slippage (special with thin markets)
I don't have experience with MCL, I just trade CL (3 contract max) and there is the slippage around 1 tick or a bit less. MCL has around half the volume of CL, but the moves should be similar, so you should use the amount of your trading experience with it.
I would recommend for any instrument first looking at the typical bid/ask spread, and using the upper end of what you see.
I have pretty detailed estimates for just about every futures market, based on statistical analysis and real money trading, but I can't freely share those.
But the spread is a good starting point for most markets (Gold would be an outlier to that rule).
