Error ReplacePendingOrders

2 replies

8 years ago #114185

Hello, we have an strategy generated by SQ running on NinjaTrader. When we run the strategy in backtest, pending orders live one bar more than in the real market or in simulation. For instance, if we have a maximum of 11 bars for the pending order, then in backtest the pending order gets cancelled at the eleventh bar but in the real marked it gets cancelled at the tenth bar. How can this be possible? Is there any possible workaround?

Thank you.

Not sure what could cause this. Maybe it has something to do with “evaluate on bar close”. So in live/sim the order is deleted while the bar is being created but in backtest it’s evaluated once bar closes … that’s why there is 1 bar increment

See here “Running a Strategy at the Close of a Bar or Tick by Tick”

¢ During backtest, strategies can ONLY be processed at the close of each bar

¢ During real-time operation, you have a choice to run a strategy tick by tick (CalculateOnBarClose set to false) which can produce different results

Ok we are going to try setting CalculateOnBarClose to true. If this doesn’â„¢t work we will tell you.

Thanks.

Hypothetical Performance Disclosure:
Hypothetical performance results have many inherent limitations, some of which are described below. no representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
