Mini Coil With Real Range

A mini coil is a low risk setup that can be used within a longer term pattern. The coiling action represents a tightening of volatility and is most effective when price is no more than 10-15% above a prior base.

The mini coil was created by Matt Caruso, @CarusoInsights, a professional investor and top performer in the 2020 US Investing Championship, finishing with a 346% return.

Mini Coil Setup
▪ Given an initial bar, at a minimum, two bars follow that don't exceed the high or low of the initial bar.
▪ The entry is when there is a break above the high of the initial bar.
▪ A common stop is the low of the last bar before the breakout.

Unique Features
▪ Real Range
When the initial bar open is a gap up greater than the previous bar close, when using the real range, the start of the mini coil is the close of the bar prior to the gap up. See the examples below for more information.

▪ Thresholds
During the formation of a mini coil, price may deviate slightly above or below the high or low of the initial bar. It can be helpful to set a threshold which allows for small percentage moves, above or below, yet still consider the price to be within the high/low range of the initial bar.

▪ Breakout Price
To help track the potential breakout price, there is an option to show the high of the initial bar.
