Tradingview to Binance: open a buy/sell order with strategy

Please advice on how to setup a combine buy and sell order on a strategy alert triggered on binance.

I used :
{{strategy.order.action}} BTCUSDT q=20%
it bought for me but after buying when the selling alert is triggered nothing was done.

I tried using:
{{strategy.order.action}} BTCUSDT q=20%
Sell ONGUSDT Q=100%

this message also did not work.
{{strategy.order.action}} BTCUSDT q=20%
{{strategy.order.action}} sell BTCUSDT q=100%

they were just buying and not selling when the sell alert is later triggered.
Please what should be the message for strategy alert to trigger buy and then sell

Hello @elhigh

This is a perfect case where we use multicommands. Each command will start on a new line as shown below:

{{strategy.order.action}} BTCUSDT Q=50% A=USDM
