Now my strategy is

1. Open long position on 5-minute OBV-EMA golden cross (crossing up); close position on 10-minute death cross (crossing down)

2. Open short position on 5-minute death cross; close position on 10-minute golden cross

The strategy trading on OKX can execute TV alerts well, but it should be noted that I am using Binance data, so in the alerts you need to change "{{ticker}}" to "BTC-USDT-SWAP", otherwise it will report an error.
