Hello SteveReiza,

The warning that you have shown will not disable a strategy, that is just letting you know the strategy tried to place a historical trade very early on in processing. The default bars required to trade is 20 bars so the strategies condition to trade become true before that point and the order was ignored.

thanks for the reply. some of my strategies are no longer enabled after it happens though. alright is there a reason its trying to place a historical trade?

Hello SteveReiza,

That would be for a different reason then. The warning that you pictured is not something that can disable a strategy, there are also no disabled strategies being listed in that image.

The reason its trying to place a historical trade is because your condition to trade became true. A strategy trades based on the conditions that you make. When you apply a strategy it runs over the bar series and does a historical backtest before entering realtime.

two of my strategies execute. but i have other ones that don't. and, i see their entry methods on the chart happening and no execution from the automated strategy occurs. they are simple too just price below bollinger 3 bars ago. 2 bars ago low below bollinger, high above bollinger. and 1 bar ago close above low + 20 ticks - then enter. i have a lot of strategies similar to this. and none of them are entering.

Hello SteveReiza,

It is best to test a single strategy at a time so you can identify what is happening, until you know what you made works well that will help with diagnosing problems. Comparing strategies that have different logic would not be a good way to identify problems, you will need to test and debug each strategy individually.

Looking at the chart to see if entry conditions are met is not the same as knowing the logic worked, you would need to add prints into the script to identify if the condition to trade was true or not. You can also use TraceOrders to check if orders are being ignored for any reason.

thanks for the reply. i see where i can select trace orders in the strategy builder. where do i read the output at? the output window? do i have to do print with that?

[NinjaTrader_Jesse]

Hello SteveReiza,

Yes that goes to the output window. You need to remove and re apply the strategy when changing the strategies default settings. Prints would also go to the output window but would be for your own use, you can use prints in conditions to see if they are true or output values to know what the strategy is seeing logically.

thanks for the reply. alright sweet. i'll check into both trace and print and see what's going on. thanks for the guidance.
