Changes

Limit orders are filled at a specific price or better (for long better = lower, for short better = higher). In backtesting MultiCharts either works :* Either with all prices between Open, High, Low, Close of a bar, [[Intra-bar Price Movement Assumptions|assuming that all these prices are real]]; or * Or with specific prices only, when 1 tick resolution is chosen or [[How Signals are Calculated|Bar Magnifier]] is used.

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