# 3-in-1 Simple or Exponential Moving Average for ThinkorSwim

Here is a multi-moving averages indicator for ThinkorSwim so that you can easily add more than one simple or exponential moving averages without adding multiple indicators. Normally if you want to add a 5 and 10 SMA into your chart, you would need to include 2 different inputs and 2 copies of the same indicator. Now you don't have to. With this indicator, you can include 3 SMA or EMA into your chart in a single indicator.

The indicator is fully customizable and includes crossover signals (Bullish and Bearish) as well.

If you only use 2 moving averages, here is the 2-in-1 version. Same functionality.

@BenTen Will this ideally work via day trading?

@Likos Thats up for interpretation. Depending on your selected MAs and how you like to use it.

The "3-in-1 Simple or Exponential Moving Average" indicator has a section "define e-signal and crossover point". Does this issue an esignal (SMS) and alert at the crossover point to email and text?

@mrstair Unfortunately it does not. The developer just named it e-signal. Had nothing to do with SMS alerts.

I'm wondering if a scan can be done when price H is moving above the 3moving averages(ema) which are stacked. Thanks so much.

@tenacity11 By stacked do you mean just generally above the EMAs or the crossover?

I'm looking at the crossover where the 5 and 10 are together and cross above the 20. thanks

Thanks for the reply but I could not find anything

Thanks for the reply but I could not find anything
What do you mean? No one can help you if your not specific. Just for fun, I clicked on the link above and it works. There is no way you could go through that onenote section in 8 minutes. It took me that long to find the right section for you. What you are looking for is something like plot_scan, plot scan, or something in the moving ave. section of the scans in one note to copy-paste into your script to make it scan. There is a section in there called "How to drive the scanner"., read that. The second tab from the top in the OneNote says the Manual. Look for a template there. Good Trading, Markos

Well actually I've been going through that whole area beginning last night. I will go through what you suggested and thanks again.

You can just simply scan for 5/20 crossover. If you think about it the 10 MA is faster than the 20 MA. If 5 MA crossing the 20 that means it also already crossed the 10

That's what happens when you over think. A big fat DUH to me. Thanks Ben for pointing that out.

@john3 I think because the fastest EMA didn't crossover the other two MAs within 1-2 bars.

@BenTen This is an useful indicator as well as time saving. Can you help to put on an alert script for the "up" and "down" signals? Thanks !

@BenTen Thank you ! you are the best !
