Hi Bruce,

Is it possible to plot this line indicator on the chart against a ticker as I can't find it in the Indicator list. If so, could you tell me how to do it using an RSI of 50 please? I've put a few info sources below to help.

Thanks very much.

Please try the following indicator (it assumes a 14 period Wilder's smoothed RSI).

C + 13 * XAVG(ABS(C - C1), 27) - 26 * XAVG(IIF(C > C1, C - C1, 0), 27)

Blimey, I'd have never have worked that out!

Thanks very much Bruce.

If you are just interested in determining if Wilder's RSI5 has crossed up through its own 3 period exponential moving average.

XUP(WRSI5, XAVG(WRSI5, 3))

If you are just interested in determining if Wilder's RSI5 has crossed up through its own 3 period simple moving average.

XUP(WRSI5, AVG(WRSI5, 5))

Please try the following.

XUP(WRSI5, HAVG(WRSI5, 3))

Big congratulations, thank you!
Sincerely !

You're welcome.
