Hellow,
I am currently using https://testnet.binance.vision/ to test APIs for demo purpose. In the beginning, I was able to use all authenticated APIs like sell/buy order, cancel order, get all orders etc with the following URL on postman: https://testnet.binance.vision/api/v3/order?symbol=BTCUSDT&side=BUY&type=LIMIT&timeInForce=GTC&quantity=10&price=400×tamp={{timestamp}}&signature={{signature}}
but I have been getting this error: {code: -1013, msg: ‘Filter failure: PERCENT_PRICE’}.
I also used npm package ‘binance-api-node’ but got the same error. Also, I created a new account on binance testnet and tried with different apis but got the same issue. I tried with different symbols but no luck.
