Breakout asia USD/CHF

1 — Customizable Parameters
sess1 & sess2: The two time ranges that define the Asian session (e.g., 20:00–23:59 and 00:00–08:00).
Important: format is HHMM-HHMM.

rr: The risk/reward ratio (default = 3.0, meaning TP = 3× risk size).

onePerSess: Toggle to allow only one trade per Asian session or multiple.

bufTicks: Extra margin for the SL beyond the signal candle.

2 — Detecting the Asian Session
The script checks if the candle’s time is inside the first range (sess1) or inside the second range (sess2).

While inside the Asian session, it updates the current high and low.

When the session ends, it locks in these levels as rangeHigh and rangeLow.

3 — Step 1: Detecting the Initial Breakout
Bullish breakout → close above rangeHigh → flag breakoutUp is set to true.

Bearish breakout → close below rangeLow → flag breakoutDown is set to true.

No trade yet — this is just the breakout signal.

4 — Step 2: Waiting for the Retest
If a bullish breakout occurred, wait for the price to return to or slightly below rangeHigh and then close back above it.

If a bearish breakout occurred, wait for the price to return to or slightly above rangeLow and then close back below it.

5 — Entry & Exit
When the retest is confirmed:

strategy.entry() is triggered.

SL = behind the retest confirmation candle (with optional bufTicks margin).

TP = entry price ± RR × risk size.

If onePerSess is enabled, no further trades happen until the next Asian session.
