OPEN-SOURCE SCRIPT
Updated Moving Average Exponential with Standard Deviation Band

This is standard EMA script available on Trading View and i have just added ability to add a channel based on standard deviation. In addition to it you can enable/disable optional lines from options and it would add 50% levels of upper and under channel. I added 50% as it provide important price levels if you have right settings selected for channel factor.
