### EDITOR'S COMMENTS
Made any edits? Why not explain here.
###

### DONATIONS
I am releasing this as a donation based bot. I am releasing this in hope of obtaining some donations from users here.

### DISCLAIMER
As usual with all trading, only trade with what you are able to lose.
Start small.
I am NOT responsible for your losses if any occur.
###

### CREDITS
The VIX and Swing indicators used here were originally by Chris Moody at TradingView.
Trading logic is my own.
Thanks to all at Cryptotrader.org that helped me along the way.
###

### ADVICE
Rather than just trading with this, I strongly recommend making this bot your own.
Use it as a learning tool.
Edit it to trade as you like to match your strategy.
View this as a template for a long term trend trader with added scalping.
Backtesting is your friend. Backtest over long periods to identify strengths and weaknesses.
