1. Open an RSI
2. Click on a new RSI in the menu and hold and drag it into the window with the already opened RSI
3. Where it says something like "apply" or "apply to" close, open, etc, change it to first indicators data.
If it doesn't work, mention which MT4 broker you use and I am sure someone with that broker can help you out.
