Prevent entry at the same price level more than once within a session

[suprsnipes]

Hi guys,

I would like to ask if you could point me in the right direction as to how I could achieve the following.

If within a session an order has already been executed at a particular price level I want to prevent the strategy entering another limit buy or sell trade at that previous level.

suprsnipes, you would then need to save the price level for example to a variable and check if new orders outside of a certain range around this to be considered valid...then reset the variable on session breaks to 'arm' it for all trades to be considerd for the new day.

Can I achieve this within the strategy wizard?

Unfortunately this would require custom programming suprsnipes.

What section of the NT help guide can you refer me to then?

[NinjaTrader_Bertrand]

You would either need to save your execution / entry signal prices to variables as you go, or access the IExecution's of the strategy directly through the Trade class - http://www.ninjatrader-support.com/H...radeClass.html

Thanks for the reply Bertrand,

Is there a code snippet that you can provide?

Unfortunately I'm not aware of one related to this topic.

Could I use Position.AvgPrice?

If so to achieve this where would I need to add the code?

From what I have be reading this could possibly be both in the variables section as well as the OnBarUpdate section within NinjaScript?

I'm just a little uncertain as to where I should look to add the code I require...I looked into IOrder also but that seems like a more advanced level of programming.

Position.AvgPrice would just give you the entry of the current, open position - you would need to access the history for positions you took to check if it falls within an already taken trade and thus it should not be executed.

This would indeed require some custom programming - perhaps it's good idea to contact a NinjaScript consultant to assist you -
