Bittrex Bot buy at ask I am trying to write a bot to use it on Bittrex with nodeJs, but the documentation is very poor. My problem is that I would like to be able to buy the last ask, like when in the web you click in bid the option ask, this way the buy is instant.
For developing the bot I am using:
 https://github.com/n0mad01/node.bittrex.api
I have tried:

 bittrex.buyLimit({ market: 'BTC-ETH', quantity: 0.001, rate: "ask"}, function (data) {
    console.log("Response: " +data);
})


but it does not accept the rate "ask", is there any way this can be done?
Check the Bittrex api page.

The buyLimit endpoint says that the rate must be the rate at which to place the order.

In order to get the current ask price, use the getticker api which will return something like:

{
    "success" : true,
    "message" : "",
    "result" : {
        "Bid" : 2.05670368,
        "Ask" : 3.35579531,
        "Last" : 3.35579531
    }
}
