Increasing the overbought input makes the trigger more precise, but it may not trigger as often. Decreasing the oversold input will do the same for that trigger.
You can adjust the alerts and the overlaid position suggestions to match your preferred leverage amount.
To set an alert, click "add alert", then select this script. Choose one of the oversold or overbought alerts and enter your message.
I primarily use this on BitMEX with BTC , but you can use it with other exchanges and coins. You may have to adjust the inputs depending on the coin and the timeframe you use. Do not blindly follow this to make purchases. This is just an alert system to notify you of possible trades.
