why return 404 when i run this script ?? i think is correct ,
#!/bin/bash
APIKEY="MY API KEY"
APISECRET="MY SECRET KEY"
#sURLPART2="symbol=BNBUSDT&side=BUY&type=LIMIT"eOrderQty=10&price=270.3&newOrderRespType=FULL"
URLPART2=""
RECVWINDOW=50000
RECVWINDOW="recvWindow=$RECVWINDOW"
TIMESTAMP="timestamp=$(( $(date +%s) *1000))"
QUERYSTRING="$URLPART2&$RECVWINDOW&$TIMESTAMP"
SIGNATURE=$(echo -n "$QUERYSTRING" | openssl dgst -sha256 -hmac $APISECRET | cut -c 10-)
SIGNATURE="signature=$SIGNATURE"
curl -H "X-MBX-APIKEY: $APIKEY" -X POST "https://api.binance.com/api/v3/account?$URLPART2?$RECVWINDOW&$TIMESTAMP&$SIGNATURE"
echo
