Reasons a stop/loss order does not get triggered?

[cmarkb]

We're doing backtesting with our strategy. Using FDAX and Tick Replay. The strategy also use our own indicator which produces a value that's used by strategy to determine when to submit an entry order. Strategy uses Calculate.OnBarClose while indicator uses Calculate.OnEachTick.

We send orders using SubmitOrderUnmanaged() and implemented trailing stop using chargeOrder().
Noticed that some of the stop/loss orders don't get triggered.
Are there rules about when a stop/loss order will get triggered or not?
Thanks.

Here's a sample log showing when stop order is changed (using TraceOrders and OnOrderTrace) and current price via OnMarketData.
Dates below are in GMT+8.

Stop price gets updated to 11509.5 near 27/05/2020 00:39:23.537000.
Price goes down to 11509, 11508.5,11508 on 27/05/2020 00:42:30.139000.
Stop/loss gets triggered later on 27/05/2020 00:47:59.991000.

Hello cmarkb,

The first issue is that the Calculate needs to be the same between the host and hosted script.

https://ninjatrader.com/support/foru...24#post1118724
https://ninjatrader.com/it/support/f...62#post1127162

Set the Strategy to Calculate.OnEachTick, and trigger all actions when IsFirstTickOfBar is true.


Second, as a heads up, TickReplay does not provide fill prices for accurate order fills. Orders will still be filled without tick granularity within the larger bar.

https://ninjatrader.com/support/forum/forum/ninjatrader-8/strategy-development/94098-isfirsttickofbar-vs-onbarclose-for-backtest-live?p=773377#post773377

For a live order placed to your broker, contact your broker with the order ID and ask why this order did not fill while it was in a working state.

In sim real-time or playback, I would recommend opening a 1 tick ask chart and a 1 tick bid chart. Mark the time when the order becomes working, when the price is changed, and when the order is cancelled. For a buy order check every ask tick to see that there is an ask tick that would have filled the order. For a sell order check every bid tick to see there is a bid price that would have filled the order.

For historical orders, I would recommend enabling TraceOrders and directing this to file, writing the time and value of every bar high and low to file (if no intra-bar granularity is added for accurate order fills, print a 1 tick series values if intra-bar granularity for accurate order fills is added), and writing the order.ToString from OnOrderUpdate() to file.

Below is a link to an example.
https://ninjatrader.com/support/foru...nce#post100192

Basically, you want to analyze when the order actually becomes working, mark the time of every price change, and when it is cancelled, and check the fill bar price information to verify that a valid price was received to fill the order while the order was in a working state.

Hi Chelsea,

Thanks for the reply.
Have been reading the other posts you've linked which helped big time.
Will post additional questions here when I'm stuck. Thanks.
