Bitcoin: BARR - Bump and run reversal (Bulkowski)

Lead-in: angle not too flat, not too steep - visual assessment okay (scale varies, ~25-50 degree angle for reference)
Bump: angle should be ~50% greater than lead-in angle
Bump validation: distance from bump line to highest high should be at least 2x the distance of lead-in line to highest high
Reversal: look for top patterns and descending peaks
Run: once lead-in line support is broken, large decline occurs - sometimes retested and support becomes resistance
