Position setting is done for Binance-Futures, so that whenever Tuned emits a signal, it should be either Long or Short. Tuned doesn't support opening both the Long and Short contracts at the same time which is known as Hedge-Mode within Binance-Futures exchange.
In order to prevent execution failures, position setting should be set to One-Way Mode.
How to set it to One_Way Mode ?
Login to Binance Exchange, and select Futures exchange
Next, Click on Preference
Click on Position Mode, One-way Mode and Confirm
And that's it.
