Can't buy and sell futures and catch market prices in variable

API Futures API
1

Hi, i have the api working well for spot market price SELL and BUY
but about futures market price SELL and BUY i can’t get it work, despite i
have a future account that i used previously.
i tried theses 3 ways (at least) and fo 2 i have this Promise { }
responses.

console.info( binance.futuresMarketBuy( ‘ETHUSDT’ , 0.0085) );

console.info(binance.futuresMarketBuy( ‘ETHUSDT’ , 0.0085, { newOrderRespType: ‘RESULT’ } ) );

binance.futuresMarketSell( ‘ETHUSDT’ , 0.0085 );

also, i don’t understand how to catch the informations in variables with this streaming feed binance.futuresTickerStream( ‘BTCUSDT’ );
which stream i can’t stop.

Theses are also not working
console.info( binance.futuresLeverage( ‘ETHUSDT’, 50 ) );
binance.futuresLeverage( ‘ETHUSDT’, 50 );

thanks in advance for the help

Pure nodeJS problem. Please use below as resolve function:
binance.futuresMarketBuy(‘ETHUSDT’, 85).then(resp=>console.info(resp))
For further clarification, please go to a nodeJS dev forum to discuss
