Number of ticks to use for "Fill limit order when trade price goes beyond limit price by"

Hi all,

I'm working on a strategy that trades Forex and utilizes limit orders.

My question is, what is the appropriate number of ticks to use for the setting "Fill limit order when trade price goes beyond limit price by." Should this be set to the spread of the currency pair? For example, if EurUsd has a spread of 3 ticks then set that parameter to 3 to account for the spread? If the spread is 3 ticks, and I have the parameter set to 1, I'm worried that it won't account for the bid price hitting a sell limit or the ask price hitting a buy limit.

Any help is appreciated.
Thanks

Hi AnotherTrader,

For spread emulation we'd recommend using Precise Backtesting.
