VRSI+EMA+BBands

I am new to the stock market world and have only been studying it for about 2 months now, I have been trying to practice some pine script because it is a good tool to have when doing technical and statistical analysis. I created this study with 3 indicator on it I have taken some of the work from the forum and revised it my self to make it look like how I want it. The 3 indicators in this are vrsi, double emas and bollinger bands. These are some of the indicators I use to make well protected trades. I hope you enjoyed this and finds it useful, I know that I am new to this so please dont be hard.
