Overview
Structure TA marks swing highs and lows, break of structure and change of character events, optionally with an inducement step, and shows internal structure and volume on major swings. It also draws previous day high and low lines, an optional equilibrium line, sweep lines with markers, target levels and live structure breaks. Optional session shading and a daily bias explanation can be switched on, with a seasonal time adjustment. It is based on another author's script credited in the code.
- Break of structure and change of character labels
- Choch with or without inducement
- Previous day high and low and equilibrium lines
- Liquidity sweep markers
- Session shading and bias reasoning options
