Checking ATM Market Position

[spencerduran]

is there a better way to check for position when using an atm in a strategy? I'm getting the error on every price change:
'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter
'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter
'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter
'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter

'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter
'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter
'GetAtmStrategyMarketPosition' method error: Missing ATM strategy ID parameter

I'm currently using

if (GetAtmStrategyMarketPosition(atmStrategyId) == MarketPosition.Flat)
            {
              ExecuteLongEntry();
            }​

The error seems like it would be expected, since there isn't an open position, but for it to be constantly echoing this makes me think there might be a quieter way to check?


Second piece, what is the way to check position quantity when using ATMs? The following doens't seem to work:

          if (GetAtmStrategyPositionQuantity(atmStrategyId) < 5)
          {
            ExecuteShortEntry();
          }​

Hello spencerduran,

Ensure the Atm is started by checking the isAtmStrategyCreated bool is true. (This should be set to true in the AtmStrategyCreate() callback).
Ensure GetAtmStrategyEntryOrderStatus(orderId)[2] is "Filled".
Ensure the atmStrategyId is the same that was provided to AtmStrategyCreate and this has not changed or been set to an empty string.
This should prevent the error by ensuring the entry has filled and the Atm is active.

Thanks

So to check if flat, i would first check if the strategycreated bool is false?

Also, the second part of the question:
what is the best way to find atmstrategypositionquantity?

Hello spencerduran,

Yes, if the Atm is not active yet, there will be no atm object with a position to check, so an error will occur.

GetAtmStrategyPositionQuantity() is the best way to get the atm position quantity, but only after the atm is created and the entry order has filled.

That seems to work

is it possible to add an additional atm order to increase position quantity? I think since this only works when the atmStrategyId.Length == 0, i need to change something about the first part of ExecuteShortEntry()

Hello spencerduran,

There isn't a way to scale into an existing Atm through NinjaScript.
You could choose to start a second atm, instead of scaling in.
Or we often suggest instead, placing an order to the account and then adjusting the quantity of the stop and limit orders to cover the quantity of the new entry.
