Why why can I not sell the same quantity as I bought?

API Spot/Margin API

Hi

I have created a buy market order for BTCEUR 0.0002 and that worked.

I then get the latest price for the symbol.

I then wanted to create a limit order, I pass in the same quantity and a price

but then I get this error:

I do a post like this:
https://testnet.binance.vision/api/v3/order?timeInForce=GTC&quantity=0.0002&price=53525.979&symbol=BTCEUR&side=SELL&type=LIMIT&timestamp=1726236848987&signature=xxxxd`

resulted in a 400 Bad Request response:
{“code”:-1013,“msg”:“Filter failure: PRICE_FILTER”}

What do I miss ?

The current PRICE_FILTER settings in testnet for BTCEUR are

        {
          "filterType": "PRICE_FILTER",
          "minPrice": "0.01000000",
          "maxPrice": "1000000.00000000",
          "tickSize": "0.01000000"
        },

Note the tickSize, which allows only increments of 0.01 EUR. At the moment you cannot use price 53525.979, you need to round it to 53525.97 or 53525.98.
