RSI of a Moving Average

[monti1a]

I need help in designing an indicator which plots the RSI of a Moving Average. The default values for the moving average should be (10 Period, EMA), and the length of the RSI should be 5. Any help would be greatly appreciated.

Thanks

You may want to try to do that using the Formula Wizard's study on study feature.

Alexis-

I actually tried the formula wizard but it doesn't return any plot.

The code that was created is as follows:

Any help would be greatly appreciated.

The errors were in the definition of the RSI study and in the return statement. The enclosed revision fixes both.

I greatly appreciate the help Alexis. Thanks a bunch. I have one final problem. I'm trying to add two bands (25 & 75), and I have tried everything however, they will not plot at all. The code that I am using is:

addBand(25, PS_SOLID, 1, Color.black);
addBand(75, PS_SOLID, 1, Color.black);

I simply added this code into the preMain section just as the EFS guide suggested, however, they will not plot.

Help from you or anyone else would be greatly appreciated

Try

addBand(25, PS_SOLID, 1, Color.black, 99);
addBand(75, PS_SOLID, 1, Color.black, 98);

The tag identifier is required for multiple bands.

The enclosed revision will plot the bands
Alex

Edit after post: Note that if you insert the addBand() command in main() you will need a tag identifier as suggested by David Loomis

Thanks to all - Alexis and David for your input. You both have been very helpful.

To other esignal users, I have found the RSI of Moving Average Indicator to be a very powerful tool for identifying when prices have become overextended and as a result, a very strong snapback usually ensues.
