OnExecution() PartialFills

[shiva_mohan]

Question re the sample posted on http://www.ninjatrader.com/support/f...ead.php?t=7499

When submitting target / stop orders in the OnExecution method, in the sample, we have ...

if (execution.Order.OrderState == OrderState.Filled || execution.Order.OrderState == OrderState.PartFilled ... ) {
// Stop-Loss order 4 ticks below our entry price
stopOrder = ExitLongStop(0, true, execution.Order.Filled, execution.Order.AvgFillPrice - 4 * TickSize, "MyStop", "MyEntry");

// Target order 8 ticks above our entry price
targetOrder = ExitLongLimit(0, true, execution.Order.Filled, execution.Order.AvgFillPrice + 8 * TickSize, "MyTarget", "MyEntry");

Should the order quantity given to the stop and the target order be execution.Quantity instead of execution.Order.Filled? Because lets say we have an entry order with 10 contracts ... we get a partial fill of 4 contracts and then a second partial fill of 6 contracts. If we use execution.Order.Filled, then wouldn't that mean that first a stop + target order will be sent for 4 contracts and then instead of sending an additional order for 6 contracts, an additional order for 10 contracts will be sent.

Please let me know if my understanding of execution.Order.Filled versus execution.Quantity is correct.

Hello shiva_mohan,

execution.Order.Filled is what you will want to use here, even in partial fill cases. You can test this in a simulated environment by enabling enforce partial fills, under tools > options > simulator tab.

Change the order quantity on the enter method to something like 200, and run in real time. You will get partial fills but the resulting quantity of the target and stop loss orders will be 200.
