How to place Bid and Ask Order NT8 API DLL

[smartromain]

Hi,

I trying to place a bid and ask orders with the API DLL and NT8 using VS.

I don't really understand what this suppose to do:

int Ask(string instrument, double price, int size)
Sets the ask price and size for the specified instrument. A return value of 0 indicates success and -1 indicates an error.

and

int Bid(string instrument, double price, int size)
Sets the bid price and size for the specified instrument. A return value of 0 indicates success and -1 indicates an error.

What price I'm suppose to write?

                        
int Ask = myClient.Ask(contract, 0, qty);
Console.WriteLine($"Ask: {Ask}");​

Help me understand.
Thank you

Hello smartromain,

Use the Command() method to submit an order. For the ACTION parameter supply the string "BUY" for a buy order and "SELL" for a sell order.

int Command(string command, string account, string instrument, string action, int quantity, string orderType, double limitPrice, double stopPrice,
string timeInForce, string oco, string orderId, string strategy, string strategyId)

The Ask() method is used when sending data from your application to the External Data Feed connection in NinjaTrader.

I know how to place Market order, we set the price to 0 in double limitPrice, double stopPrice.

But how to place bid and ask order, in NT8 in panel Basic Entry there is Buy Ask, Sell Ask, Buy Bid, Sell Bid, no need to enter price.

I'm trying do to that with this Place order command int Command(string command, string account, string instrument, string action, int quantity, string orderType, double limitPrice, double stopPrice, string timeInForce, string oco, string orderId, string strategy, string strategyId)

Hello smartromain,

Unfortunately, these actions in the Basic Entry are not directly available to the API or NinjaScript. Clicking the Buy Ask button in the Basic Entry actually causes NinjaTrader to just submit a regular limit order and supply the current ask as the limit price.

Your application would have to do the same. Fetch the current ask, supply this to the Command() method as the limitPrice.
