[testnet] The counterparty's best price does not meet the PERCENT_PRICE filter limit

Getting this error when submitting MARKET orders :

{"code":-4131,"msg":"The counterparty's best price does not meet the PERCENT_PRICE filter limit."}

Also, LIMIT orders not getting filled (even placing from WebUI).

Is testnet operating correctly? How do I go about testing API endpoints if testnet ghosting like this?

I’m afraid it’s caused by no liquidity from the testnet. Would you like to try with another symbol with more open orders?
