Preventing live orders from submitting when backtesting

[anachronist]

This isn't a question about the strategy analyzer itself. Rather I want to ask about running a strategy on a chart.

Is there any way to prevent a strategy from sending a live order on the last bar? As a temporary fix I tried

if (!Historical) return;

at the beginning of OnBarUpdate() but it doesn't seem to matter -- if the strategy generated an order on historical data prior to the next live tick, the order gets sent.

The reason I want to prevent this is so that my ATM backtesting framework will work properly. It uses unmanaged orders on historical data, but I want it to switch over to ATM strategies on live data, and I don't want a lingering historical order to end up sitting there in the DOM ladder.

Hi Alex,

You can work with CurrentBar in relation to Count to identify the last bar on the chart. This will depend on CalculateOnBarClose settings.

bool isLastBar = CalculateOnBarClose ? Count - 2 == CurrentBar : Count - 1 == CurrentBar;

You could work that bool into your entry conditions. Pseudo code:
if (entryCondition && !isLastBar)
{
}
