Limit Order Execution Assumptions

Limit orders are filled at a specific price or better (for long better = lower, for short better = higher). In backtesting MultiCharts works:

• Either with all prices between Open, High, Low, Close of a bar, assuming that all these prices are real;
• Or with specific prices only, when 1 tick resolution is chosen or Bar Magnifier is used.

Limit order execution behavior for backtesting can be modified in the Backtesting tab of Strategy Properties window.

There are 4 different variants:

1. Chart resolution is 1 tick or Bar Magnifier of any resolution is enabled. Backtesting Assumptions is set to Fill limit order when trade takes place at limit price or better.
   Example: Generated order: sellshort limit @ 121; available prices: 120, 122, 125, ...; order is filled @ 122.
2. Chart resolution is 1 tick or Bar Magnifier of any resolution is enabled. Backtesting Assumptions is set to Fill limit order when trade price goes beyond limit price by 3 points.
   Example: Generated order: sellshort limit @ 121; available prices: 120, 122, 125, ...; order is filled @ 125.
3. Chart resolution is not 1 tick and Bar Magnifier is not enabled. Backtesting Assumptions is set to Fill limit order when trade takes place at limit price or better.
   Example: Generated order: sellshort limit @ 121; order is filled @ 121 or better if 121 (or better) is between High and Low of the bar.
4. Chart resolution is not 1 tick and Bar Magnifier is not enabled. Backtesting Assumptions is set to Fill limit order when trade price goes beyond limit price by 3 points.
   Example: Generated order: sellshort limit @ 121; order is filled @ 124 if 124 price is between High and Low; order is not filled at all if there is not 124 price between High and Low of the bar.
