BadSymbol: binance does not have market symbol BTC/USDT

• OS: Linux
• Programming Language version: NodeJS
• CCXT version: 2.2.45

My code has been running fine for a couple of years, yet today all of a sudden, I can’t fetch BTC/USDT from Binance spot market anymore. Below is the minimal code that I could use to reproduce the error.

const ccxt = require("ccxt");

async function test() {
  const exchange = new ccxt["binance"]();

  const fetchSince = Date.now() - 5 * 60 * 1000;

  const result = await exchange.fetchOHLCV("BTC/USDT", "1m", fetchSince, 5);
  console.log("result", result);
}

test();

Hello to everyone. I’m having a similar problem with the binance api (my code also runs on a US based cluster). I haven’t been able to find any official source

@ChenLi0830 exactly, We were also impacted by this, and yeah was a recent change from Binance. Basically, you will need to reallocate the instance or route the requests out of the US using a proxy

Hello to everyone. Do you have any official source for this event? I experimenting a similar problem in my USA-based cluster, and haven’t been able to find any official statement. I would greatly appreciate it if you could share it. Thanks!

Thanks that makes sense. I am closing this issue since the root cause is not from ccxt. You might want to consider using a more explicit error message though. Thanks for the good work.
