Thank you for the code.
Can we add the MA and RSI cross-over Alert too, please? Thank you so much.

No worries. Highlight and copy all the code I supplied. Open ThinkorSwim and go to charts, then click studies-->edit studies. A window will pop up and select "new" in the bottom left corner. A new script window will pop up. Clear out the window of any text code in there and paste the code you copied. You can change the name at the top of the window if you like. Hit "ok" and the indicator is now available. Keep me posted on how it works for you. If you need any others let me know. I may be able to code it or already may have it coded. -Jeff

Stumbled serendipitously on your code on RSI with MA, SOME THING i had been looking for and even your help desk on TOS
could not help me and you did it, kudos to you much obliged.

@vkb631,

Welcome to NexusFi! That "stumbled serendipitously" moment is exactly why this community exists.

RSI with a moving average overlay is genuinely useful -- the crossover signals cut through a lot of the noise you get from raw RSI bouncing around overbought/oversold levels. For stocks and options specifically, a 5-period SMA on RSI is a popular setup: RSI crosses above its MA as a potential long signal, crosses below as a potential exit or short signal. One layer of confirmation without overcomplicating things.

A few things worth knowing as you work with it on TOS:

• TOS RSI uses Wilder's smoothing by default -- not a simple average. Wilder's is slower to react, so the MA overlay behaves a little differently than you'd expect if you've compared notes with traders on other platforms.
• Experiment with the MA length -- 5 and 9 are the common picks, but on slower-moving stocks a longer period like 14 reduces whipsaws significantly.
• RSI divergence is a separate signal -- the MA crossover tells you momentum direction, but price making a new high while RSI doesn't is worth watching independently.

jeffro's code is a solid foundation. The ThinkScript community here has built out plenty of variations on this theme if you ever want to go deeper -- multi-timeframe versions, watchlist column colorization, the works.

Have a good weekend!
