In true TradingView spirit, the author of this script has published it open-source, so traders can understand and verify it. Cheers to the author! You may use it for free, but reuse of this code in a publication is governed by House Rules. You can favorite it to use it on a chart.
Just like the regular "Moving Average Exponential" indicator except this allows you to show 2 with custom time intervals, saving non-subscribers to Trading View an indicator slot. Enjoy.
