This strategy combines range, momentum and trend-following indicators to capture short-term trends. The rules are:
Calculate the price range over a period (high minus low) and smooth it to get a smooth range indicator. This measures trend strength.
Compute a momentum indicator like the Hull curve over a timeframe. The Hull curve is effective in gauging short-term trend direction and strength.
When the smoothed range indicator changes color (e.g. red to green), it signals expanding range, and a long entry is taken if the Hull curve aligns (e.g. pointing up).
When the smoothed range flips color (e.g. green to red), it signals contracting range, and a short entry if taken if the Hull curve aligns (e.g. pointing down).
Add a trend-following stop loss mechanism like exiting longs if the Hull curve turns down.
Expanding ranges with directional momentum allows fast capturing of short-term trends. Trend-following stops control risk.
This strategy uses multiple technical indicators to quickly capitalize on short-term trends. Compared to long-term strategies, it trades more frequently to capture price swings. Strict stops are required to control risks.

// Designed for the purpose of back testing
// Strategy:
// - When the Range Filter Color Changes, And the HULL Suite is in that direction, Enter In that direction
// - e.g Range Filter Changes color from red to green, and Hull Suite is in Green. Enter Long
// - e.g Range Filter Changes color from green to red, and Hull Suite is in red. Enter Short
