Is it possible to ensure the trade only occurs at a particular price

[ppau2004]

Is it possible to ensure the trade only occurs at a particular price? Either fill or cancel if it can't be filled. But do not enter on a different price ?

Account: Sim
Example:
Chart->Right Click->Place a sell limit stop order at 3478.75, quantity =7 ->Wait till order Filled ->Buy all of them at any market price ->Order filled

Result:
1) Checked Order details, system automatically set the sell limit stop includes stop price 3478.75, and a limit price 3478.50
2) 5 of the orders showing entry price at 3478.75, but 2 orders showing entry price at 3478.50.

I only want 3478.75, or no fill.
How can we do that ?

Hello ppau2004,

Thank you for your note.

That would be what's referred to as a "Fill or Kill" order.

NinjaTrader 7 and NinjaTrader 8 do not support Fill or Kill orders. A Limit order may leave some contracts in open if it receives a partial fill, and market conditions do not allow the rest of the order to fill.

If you want to guarantee a fill once the market touches the price you want, you could use logic to call a market order once the price touches the desired price. If using NinjaTrader 8, you could use Market If Touched orders instead of Limit orders which simulate this behavior on your PC. (Once NinjaTrader sees the price touches, the Market order is submitted. The order does not reside at the exchange.) These orders may incur slippage as opposed to Limit orders, however.

Let us know if you have any additional questions.
