I use this indicator for testing with alerts and Autoview for buy signals. There are no sell signals, so that is entirely up to you. The goal is to catch the bottoms of small swings buy layering in. You can adjust the base sensitivity as well as how far down it's looking to buy. The buy plots are absolute locations - so where they lie, is where the buy signal alert will fire. Autoview will attempt to place a trade at the time of the alert. The goal here is to buy under the base and sell on the way up or at the support level.
How you use this is entirely up to you. I just play around with these alert signals for testing profitability. If you use this for buying alerts, you're using them at your own risk.
The average base crack % is going to be the lowest layer shown, and the other layers will go up from there. There are 5 layers.
Example: Average Base Crack is 5%
Layer1 = 1% , Layer2 = 2%, Layer3 = 3%, layer 4 = 4%, layer 5 = 5%
Example2: Average Base Crack is 10%
Layer1 = 2%, layer2 = 4%, layer3 = 6%, layer4 = 8%, layer5 = 10%
