📌 Logic Breakdown
✅ Swings
Swing High: A candle’s high is greater than the highs of all N candles on both sides.

Swing Low: A candle’s low is lower than the lows of all N candles on both sides.

💧 Liquidity Sweeps
Sweep High:

Price spikes above a previous Swing High,

Then closes back below it (false breakout).

Sweep Low:

Price drops below a previous Swing Low,

Then closes back above it.

🔁 Break of Structure (BOS)
A BOS is only shown if:

It occurs after a valid sweep (within X bars),

It hasn’t been already plotted for that sweep,

BOS ↑ is only possible after Sweep Low,

BOS ↓ is only possible after Sweep High,

Opposite BOS type resets the last BOS state.

BOS ↑ (Bullish):

Confirmed when price closes above previous Swing High after Sweep Low.

Label appears at the candle low.

A line is drawn from the Swing Low to the BOS candle.

BOS ↓ (Bearish):

Confirmed when price closes below previous Swing Low after Sweep High.

Label appears at the candle high.

A line is drawn from the Swing High to the BOS candle.
