Elder Impulse System with AutoEnvelope combined by idu

The idea is to combine Elder Impulse System with AutoEnvelope. It's usefull for free accounts to have more indicators on chart.
So what would on chart:
- fast ema
- slow ema
- AutoEnvelope
- Bar colour changed after signals of upcending/discending fast ema + upcending/discending macd

I've used Elder Impulse System by samuel16 and Elder's AutoEnvelope indicator by jamiespips. Thanks to both of them.
