Command Parameter 'SIM101" is unknown

[Mabaturova]

Hello! I have connected to ATI and am sending through orders successfully - although, the system is having a hard time recognizing the account name - I'm using "Sim101" - is there a number that's associated with the SIM accounts?

Thanks for your help!

Hello Mabaturova,

There is not a different name for the sim101 account, if you are using the ATI you would also need to make sure a default account is selected in the automated trading settings menu.

Hi Jesse!

Thank you so much for your quick response. I made the adjustment and removed Sim101 from any part of the code - I am receiving this error message:

❌ Error: Unable to retrieve last price.

so let me run a few things and see if i can fix that and will come back with any questions.

Hi Jesse & Team,

So I fixed the price and removed the need for an account, hoping to have it land on the default account (SIM101) - and am still getting these errors. I tried putting it back to Sim101 -

Why does Sim101 appear as unknown in the logs, or how to properly pass the account if an empty string is also failing?

[NinjaTrader_Jesse]

Hello Mabaturova,

It looks like the OIF string has the incorrect parameters. You need the command parameter first and then the account, you have the account and then the command.

It should look like this:

PLACE;<ACCOUNT>;<INSTRUMENT>;<ACTION>;<QTY>;<ORDER TYPE>;[LIMIT PRICE];[STOP PRICE];<TIF>;[OCO ID];[ORDER ID];[STRATEGY];[STRATEGY ID]

You need all the commas but the values with brackets [] don't need a value, the ones with <> do need a parameter.

Hi Jesse!

THANK YOU SO MUCH! It worked! It's taking in the buy/sell order - but I'm still getting an error for the stop loss:



This is the cleaned up code without any identifiers:

----------------------------------------------------------------------------------------------------------

using System;
using NinjaTrader.Client; // Reference to NinjaTrader.Client.dll

class Program
{
private static Client ntClient = new Client();

static void Main(string[] args)
{
string account = "Sim101";
string instrument = "NQ 06-25";
string action = "BUY";
double stopLossPrice = 19568.0;
double profitTargetPrice = 19600.0;

Console.WriteLine("Testing NinjaTrader Order Placement...");

// Attempt to place a market order
int mar****rderResult = ntClient.Command(
"PLACE",
account,
instrument,
action,
1,
"MARKET",
0.0,
0.0,
"DAY",
"",
"",
"",
""
);

Console.WriteLine(mar****rderResult == 0 ? "Market Order Placed Successfully." : $"Error: {mar****rderResult}");

// Attempt to place a stop order
int stopOrderResult = ntClient.Command(
"PLACE",
account,
instrument,
action == "BUY" ? "SELL" : "BUY",
1,
"STOP",
stopLossPrice,
0.0,
"DAY",
"",
"",
"",
""
);

Console.WriteLine(stopOrderResult == 0 ? "Stop Order Placed Successfully." : $"Error: {stopOrderResult}");
}
}

--------------------------------------------------------------------------

Could you clarify:
Whether the "STOP" order type is supported?
If "STOP" is not a valid order type, what alternative should I use for a stop-loss order?
Any required parameters I may be missing?

Looking forward to your guidance. Thanks!

[NinjaTrader_Jesse]

Hello Mabaturova,

STOP is not a valid parameter, you will need to reference the help guide to see the valid parameters:
