Create crossing option for limit order execution confirmation for strategy analyzer

[MarceloF]

I've been using NT for more than 7 years and I've been evaluating the backtest results a lot in relation to the real result with limit orders
My conclusion is that the state machine algorithm that NT uses to simulate the execution of limit orders could be further improved.
My suggestion is to have an option in the Strategy Analyzer panel that considers the execution of limit orders only with the crossing of the price by the order, without considering volume or anything else, only the crossing of the quotation.
With this, the generated state machine will be much closer to the real account, because in 90% of cases, to actually execute a Limit order, quotes cross the target quote.
Below is an example of how the selection option for this condition could be

Hello MarceloF,

Thanks for your post.

Please review the help guide document on the differences on real-time vs backtest (historical).
http://ninjatrader.com/support/helpG...ime_vs_bac.htm

A strategy running real-time (live brokerage account, live market simulation, Playback connection etc...) will produce different results than the performance results generated during a backtest.

When in historical data, only the Open, High, Low, and Close will be available and there will be no intra-bar data. This means actions cannot happen intra-bar, fills cannot happen intra-bar. All prices and actions come from and occur when the bar closes as this is all the information that is known.

Because of this, OnBarUpdate will only update 'On bar close' as it does not have the intra-bar information necessary for 'On price change' or 'On each tick' and the script will not have the intra-bar information to accurately fill an order at the exact price and time.

To improve the accuracy of a backtest, you may use Tick Replay along with an added 1-tick series to have logic processed intra-bar and have orders filled intrabar.
Tick Replay would be used to have the logic process OnEachTick or OnPriceChange with historical data, but this does not allow for intra-bar order fills. You would need to add a single tick data series and submit orders to that single tick data series for a strategy that uses Tick Replay.

High Order Fill Resolution allows for intra-bar order fills with historical processing, but is not compatible with Tick Replay.
