Simple but impossible to do it ... Buying and selling

[guilhem]

Hello, I am trying to do the following but cannot understand the logic of NT to do it.

Buy at limit yday high (on stop at market if market opens higher than yday high)
Sell at limit yday low (on stop at market if market opens lower than yday low)
if both orders are filled then do nothing on the close (as one stops the other)
if only one order is filled then exit on close.

Daily strategy based on minute (adddataseries(minute, 1))

can anyone help me ?

Thanks

Hello guilhem,

Thank you for your note.

With the Managed Approach you wouldn't be able to do something like this as it would run afoul of order handling rules. Specifically, with the Managed Approach, if he strategy position is flat and an order submitted by an enter method (EnterLongLimit() for example) is active and you try to submit an order that is used to open a position in the opposite direction, the second order will be ignored.

You would need to use the Unmanaged approach to submit the orders as that approach is not subject to NinjaTrader's internal order handling rules.

It should be noted that the Unmanaged approach should be used by very experienced programmers as you would need to handle overfills, order rejections, and connection loss scenarios in your code as NinjaTrader will not manage those scenarios for you using this approach.

Please let us know if we may be of further assistance to you.

Great thanks ... I tought so but was not sure.
Is there a place where i can find how the main loop works ? when the OnBarUpDate and the others are being called ?

Thanks for you reply as always

Hello guilhem,

Thank you for your reply.

Primarily NinjaScript methods are event driven, so for example, OnMarketData() would be fired when a tick comes in. When OnBarUpdate() is triggered is dependent on your Calculate setting:

https://ninjatrader.com/support/helpGuides/nt8/calculate.htm

So, if you're using OnEachTick, OnBarUpdate() would be triggered every time a new tick comes in. With OnPriceChange it would be triggered whenever there's a change in the Last price, and OnBarClose it would be triggered once per bar, when the current bar closes.

Other methods would be called in an event driven manner as well. So, for example, OnOrderUpdate() is called when an order status changes, whether to submitted, accepted, filled, etc.

OnExecutionUpdate() would be called when an order is filled, partially filled, rejected, etc.

Further information regarding these methods may be found in our help guide here: https://ninjatrader.com/support/help...8/strategy.htm
