RQL_BOX Indicator — English Description (How to Use)
What it does
RQL_BOX is a manual range box tool controlled by two draggable vertical lines:
-
LEFT handle (v-line): selects a candle on a chosen timeframe and sets the box High/Low to that candle’s wicks.
-
RIGHT handle (v-line): defines how far to extend the box to the right (projection end).
It then draws:
-
the main box (range),
-
optional top/bottom 20% zones,
-
an optional 50% midpoint line,
-
and an on-chart info panel with key metrics.
How to use (step-by-step)
-
Choose the candle timeframe
-
InpBoxTF = the timeframe used for the LEFT candle selection (e.g., H4 / D1).
-
Drag the LEFT vertical line onto the candle
-
The box will snap to the selected candle and use its High/Low (wick-to-wick) as the box boundaries.
-
If enabled:
-
InpSnapLeftToBar = true snaps the LEFT handle to the candle’s open time.
-
-
Drag the RIGHT vertical line to set the box end
-
The RIGHT handle is only the projection end time (how long the box is drawn forward).
-
If enabled:
-
InpSnapRightToBarIfPast = true snaps the RIGHT handle to candle opens only when placed in the past (future stays free).
-
What the chart drawing represents
Main Box (Range)
-
Based on the selected candle’s wick range: Box High / Box Low.
-
Visual settings:
-
InpBoxFillColor + InpBoxFillAlpha
-
InpBoxBorderColor + InpBoxBorderWidth
-
Entry Zones (Top/Bottom 20%)
If InpShowZones = true :
-
Top 20% zone (upper part of the box)
-
Bottom 20% zone (lower part of the box)
Settings:
-
InpTopZoneColor + InpTopZoneAlpha
-
InpBottomZoneColor + InpBottomZoneAlpha
Midpoint (50%)
If InpShowMid = true :
-
A dashed 50% midpoint line across the box.
-
Settings:
-
InpMidColor / InpMidWidth
-
Info Panel (What it tells you)
The panel provides real-time metrics for the selected box:
-
Left candle TF — the timeframe used to read the selected candle ( InpBoxTF )
-
Box High / Box Low — wick-based boundaries
-
Range — Box High − Box Low (in points)
-
Midpoint — 50% level of the box
-
20% Thr — 20% of the box range (used for zone size and validation)
-
End (right) — the time where the box projection ends (RIGHT handle)
Optional 8:45 Candle Range Check
If InpUse845 = true , the panel also displays:
-
8:45 Range for the selected InpAnalysisDate , found on Inp845TF at Inp845Hour:Inp845Minute
-
A simple validity check:
8:45 range ≥ 20% of box range -
Status:
-
No Data if the candle can’t be found in history
-
Otherwise shows the range and a ✓ / ✗ style result (color-coded)
-
Typical use cases
-
Context box for intraday trading: pick an H4/D1 candle as a framework, trade reactions inside/around the range.
-
Premium/discount style zones: top 20% vs bottom 20% for directional bias or mean-reversion setups.
-
Fast visual backtesting: drag the LEFT handle across historical candles and observe how price behaves relative to the box.
Recommended default setup
-
InpBoxTF = H4 (or D1 for higher structure)
-
InpSnapLeftToBar = true
-
InpShowZones = true
-
InpShowMid = true
-
Enable InpUse845 only if you actually use the 8:45 rule in your workflow.
