I am getting node:17200 error when I am trying to place market order using node-binance-api?

API Spot/Margin API
#1

I am getting mysterious error when I try to place a market order using node-binance-api by using the following function, any suggestion is greatly appreciated!

const Binance = require(’…/node-binance-api’);
const binance = new Binance().options({
APIKEY: ‘------’,
APISECRET: ‘----------’,
useServerTime: true

});
binance.buy(“BNBUSDT”, 0.3, 0, “MARKET”)

the error I am getting is:
(node:17200) UnhandledPromiseRejectionWarning: #
(node:17200) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

binance.buy().then(resp => console.log(resp))

And it should be binance.marketBuy(“BNBBTC”, quantity) if you want to place a market order

Thank you for your response. I tried both methods you have mentioned in your comment as showing below, I am still getting the same error. Any suggestion? Thank you so much!

let quantity = 1, price = 0.069;

console.log(quantity);

//binance.buy().then(resp => console.log(resp))

//binance.marketBuy(“BNBBTC”, quantity)

I didn’t give the exact code…

Try below for a market order

binance.marketBuy(“BNBUSDT”, quantity). then(resp => console.log(resp))

And if you’re not familiar with nodeJS, don’t suggest you start real trading with its code

I tried the code you posted and now I am getting node:14868 error. I searched, I concluded that the issue should related with the code because node js error message is just indicator that there is an error in the code. I don’t have another alternative to replace node js. I have been working on this code for at least three months. I learned js and now I am comfortable using it. Do you know a group or threat might help me,

there is an example on node-binance-api to place an order. Do you have any idea how to adapt it to solve my problem ? Thank you so much

You also need to add a catch function as reject solution:

binance.marketBuy(‘BTCUSDT’,0.0006).then(resp => console.log(resp)).catch(err => console.log(err))

I suggest you get more familiar with JS regarding stuff like promise before using this SDK

#7

I will thank you buddy!

#8

Now after using the .catch… the one you suggested, I stop receving the node js error. However, now I started to see a response as shown in the attached pic. I snipped shot only part of the message because it too long

is this message mean anything to you?

Not sure how you got them; It should be like below if you do it right:

{
symbol: ‘BTCUSDT’,
orderId: XXXX,
orderListId: -1,
clientOrderId: ‘XXXX’,
transactTime: 1606829674507,
price: ‘0.00000000’,
origQty: ‘0.00060000’,
executedQty: ‘0.00060000’,
cummulativeQuoteQty: ‘11.20099200’,
status: ‘FILLED’,
timeInForce: ‘GTC’,
type: ‘MARKET’,
side: ‘BUY’,
fills: [
{
price: ‘18668.32000000’,
qty: ‘0.00060000’,
commission: ‘0.00028108’,
commissionAsset: ‘BNB’,
tradeId: XXXX
}
]
}

MJW: I really appreciate your help and time!

I am not sure how I can solve this issue. Can you help me and I will pay money for you efforts?

#12

I think I know why you got that error msg;
Please update the code to be like this:
binance.marketBuy(<your trading pair>,<your quantity>).then(resp => console.log(resp)).catch(err => console.log(err.body))

Thanks you again!

No easy way to learn it…
My suggestion is

  1. (Most important) read API doc to understand the API usage - https://binance-docs.github.io/apidocs/spot/en/#change-log
  2. Practice nodeJS skills
  3. Read source code here - https://github.com/jaggedsoft/node-binance-api/blob/master/node-binance-api.js
