Strategy Analyzer Not Calculating Long and Short Trades

[DMSCanada]

Hello Everyone,
I am working to build a strategy for trading futures and have a problem with the Strategy Analyzer.

When I run the strategy on my Sim account it shows both long and short trades, as it should, but when I run the analyzer on it the results only show profit/loss for long trades. The short trades show no activity.

Is there a setting I'm missing?

Thank you,
David.

Hello DMSCanada,

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.

Below is a link to the help guide on Calculate.

If the expected trade(s) are not appearing, this would indicate that the condition to place the order is not evaluating as true or the order is being ignored for other reasons.

To understand why the script is behaving as it is, such as placing orders or not placing orders or drawing objects when expected, it is necessary to add prints to the script that print the values used for the logic of the script to understand how the script is evaluating.

In the strategy add prints (outside of any conditions) that print the values of every variable used in every condition that places an order along with the time of that bar. Prints will appear in the NinjaScript Output window (New > NinjaScript Output window).

Also, enable TraceOrders which will let us know if any orders are being ignored and not being submitted when the condition to place the orders is evaluating as true.

Below is a link to a forum post that demonstrates how to use prints to understand behavior.

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.

Please reference the SampleIntrabarBacktest example and the following Help Guide links for more information.

Hello Brandon,

Thank you very much for the detailed explanation.

I didn't realize the OHLC were the only prices available for Historic type analysis. That would explain the location of the fill arrows on the chart.

Something I found by accident was the long and shorts trades don't show when I use the New / Strategy Analyzer window, but if I right click on the chart and select Strategy Performance they do both appear.

Thanks again and I will explore the links in your post!
