Hello itrader46, thanks for your reply.

The code you posted is OK as long as 'y' in this formula is not returning a whole number: stopPriceLong - y. 'y' would be some calculation of ticks. They do this in the example because doubles can sometime return non-whole numbers. If you did not want to do this you can confirm that 'y' is a whole number by taking the floor or ceiling of that number. See these two pages on the floor and ceiling methods:

Hello

I have a question about the floating point arithmetic: in the Sample On Order Update strategy is explained that rather than setting 4 ticks, we should be using (7 * (TickSize / 2)).

Can you please tell me why not (8 * (TickSize / 2)) and, more importantly, should I use the same method myself?

Would that have to be instead of " currentAsk <= stopPriceLong - CancelOffsetTicks * TickSize " something like " currentAsk <= stopPriceLong - ((CancelOffsetTicks + 1) * TickSize / 2) "?

In case (8 * (TickSize / 2)) would not be fine, than how would I need to rewrite my syntax in case CancelOffsetTicks = 3, 5... etc

Hello itrader46, thanks for your reply.

I was replying to this issue here in my last post:

Order ID '97e93dd5cbe94cdbb27d8592c977b317' does not exist

For high volatility, you can either run some code on the bar close using IsFirstTickOfBar or you can add a low period SMA (2-4 period) to your condition and compare the current price and that SMA. That can reduce the number of times a condition is hit. Sorry, I didn't your questions about OnOrderUpdate/ExecutionUpdate. Those will not be applicable when using ATM strategies in your script. When the script submits an ATM order it executes a command for the NinjaTrader core to carry out. We have an example here that uses OnOrderUpdate/ExecutionUpdate to submit protective orders:

https://ninjatrader.com/support/help...and_onexec.htm

[itrader46]

I posted issues with two errors, so which are you referring to?
Also, what about my questions about the timing and OnOrder/ExecutionUpdate?

[NinjaTrader_ChrisL]

Hello itrader46, thanks for your reply.

That error is coming up just because the script is calculating on each tick. There is a certain amount of time between the ATM order creation and getting back to OnBarUpdate that causes the strategy to not recognize the order ID. The error won't affect anything about the strategy. The only way around that would be to use your own stop and target orders.

[itrader46]

Hello

I've sorted out the compile error now, but I am still getting the following errors when using OnEachTick calculation mode.
This is a strategy I've adapted after the Sample Atm Strategy Reversal from NT User App Share and the original strategy prints the same errors when calculating on each tick, but when in On Bar Close, it doesn't print the errors.

I've downloaded the executions into an Excel format and looked for that order ID missing and true enough, it's not there, so what am I missing?

Is this even an issue, given that the strategy seems to run fine anyway?

Also, when I add in the " else if " cancellation code the bit that says " || SHORT CONDITION TRUE ", I'm getting some additional errors about missing ID parameter in the close method:
I can't quite get it how does it get to this error here, when I just copy-paste the syntax I am using in triggering the Short positions.

Finally, in times of high volatility, it submits and cancels so many orders in such a quick succession, that most of the times it gets it wrong eventually.

Do I have the possibility to enter an additional timing filter on top of my pullback condition given by " ...&& LONG CONDITION FALSE && currentAsk <= stopPriceLong - CancelOffsetTicks * TickSize "?
Something like: if the triggering condition becomes false and the price pulled back X ticks and more than X seconds passed, then cancel the entry order?

Should I try using the OnOrderUpdate or OnExecutionUpdate, or these methods don't apply to orders triggered by ATM? I'm not quite sure of that.

Thank you

Hello itrader46,

TraceOrders will only show information for orders that affect the NinjaScript Strategy. Atm Strategy method orders do not affect the strategy, or the strategy performance, or the strategy position, and do not trigger any order methods.
Think of these as the same as triggering a manual order.

First, what is the compile error message and what line is it on?
What is the code on that line?

Regarding the ID, what is the ID string you are supplying to the method GetAtmStrategyUnrealizedProfitLoss() call?

If you test the script included with NinjaTrader without making modifications are you able to reproduce the behavior?
Do you have an Atm Strategy template with the specific name 'AtmStrategyTemplate'?

[itrader46]

...And these are the error messages the system SampleAtmStrategy prints plus, just like I said, there are no Trace order prints, even when I copy the logic and add TraceOrders = true

The entry order average fill price is: 1491.3
The entry order filled amount is: 3

I'm struggling to do the condition of cancelling the order before execution, no matter how many variants I am doing

When I use the syntax below, from the help guide, I get the compiling error that || cannot be used with 'char' and 'string'

protected override void OnBarUpdate()
{
// ATM strategy methods only work during real-time
if (State != State.Realtime)
return;

string[] entryOrder = GetAtmStrategyEntryOrderStatus("orderId");

// checks if the entry order exists
// and the order state is not already cancelled/filled/rejected
if (entryOrder.Length > 0 && entryOrder[2] == "Working")
{
AtmStrategyCancelEntryOrder("orderId");
}
}

... while this (from Sample ATM strategy), doesn't reset the ATM id

else if (longAtmId.Length > 0 && isLongAtmStrategyCreated && (CONDITION) && (currentAsk <= stopPrice - CancelOffsetTicks * TickSize))
/*|| (longOrderId.Length != 0 && isLongAtmStrategyCreated && currentBid > stopPrice))*/
{
longAtmId = string.Empty;


... and neither do


AtmStrategyCancelEntryOrder(longOrderId);

OR

AtmStrategyClose(longAtmId);

Hi itrader46,

This error means you are accessing an ATM ID that doesn't exist in the system: GetAtmStrategyEntryOrderStatus' method error: Order ID 'ce5a...' does not exist.

Is seems like you're not using the most up to date ID for the ATM strategy. Can you confirm you are performing the ATM order submission similar to how it is done in the SampleATMStrategy code?

[itrader46]

Can you please tell me what these errors mean?

Hi itrader46,

The GetAtmStrategyEntryOrderStatus method returns an array of three strings where the order is as such:

Print("Average fill price is " + entryOrder[0].ToString());
Print("Filled amount is " + entryOrder[1].ToString());
Print("Current state is " + entryOrder[2].ToString());

This will be a good time to Print out whatever status[0] status[1] and status[2] is in your script to make sure you're making the right comparisons. The Price series collection just happens to be arrays as well, and the way you access prior data would be to iterate through the indices, but that is not applicable here.

[itrader46]

I managed in the meantime to make it reset again. It was down to me changing the "status[2]" below to "status[0]", but I can't find in the help guide what that does. Can you help me with that, please? I thought [2] is two bars ago, but it obviously isn't

string[] status = GetAtmStrategyEntryOrderStatus(shortOrderId);
if (status.GetLength(0) > 0)
{
// If the order state is terminal, reset the order id value.
if (status[2] == "Filled" || status[2] == "Cancelled" || status[2] == "Rejected")
shortOrderId = string.Empty;
}

[NinjaTrader_ChrisL]

Hello itrader46, thanks for your reply.

The Print statements need to be placed deliberately to focus on a specific part of your script. They will be called whenever the logic processes them. If you would like to limit how often you see the prints, you can use logic to control when they are called or remove the prints all together. It is often useful to add prints specifically for a section you are working on so your output is only relevant to the issue you are looking into. I'm unable to debug individual code, but I think focusing on one issue and addressing it would be the best way forward. I wanted to attach this "ATMStrategyMonitor" script that identifies and reports data on an ATM strategy using OnOrderUpdate, it could prove useful.

[itrader46]

Also, the strategies don't reset, so after a short and a long order, there is no other order in any direction
