Project Name:
Scalping Reaction Zones + Valid Order Blocks
MAIN GOAL
I need a custom TradingView indicator for scalping.
The indicator must detect:
1. Reaction / Explosion Zones
2. Valid Order Blocks
3. Combined Reaction Zone + Order Block zones
The indicator should NOT generate:
Buy signals
Sell signals
TP
SL
Entry signals
Trading recommendations
The main purpose is to detect strong price zones where price moved aggressively from and where price may react again when it returns.
TIMEFRAME LOGIC
Each timeframe must work independently.
M1 chart = use M1 candles only
M5 chart = use M5 candles only
M15 chart = use M15 candles only
M30 chart = use M30 candles only
H1 chart = use H1 candles only
H4 chart = use H4 candles only
If I change the timeframe, the indicator must recalculate all zones using the current chart timeframe only.
Do not mix zones from different timeframes.
Default mode:
Current Chart Timeframe Only
REACTION / EXPLOSION ZONES
The indicator must detect a small BASE candle or opposite candle before a strong price expansion.
Bullish example:
Small bearish candle or small base candle
Then strong bullish displacement
The original candle becomes a DEMAND / REACTION ZONE
Bearish example:
Small bullish candle or small base candle
Then strong bearish displacement
The original candle becomes a SUPPLY / REACTION ZONE
Default zone boundaries:
Full candle High to Low
Optional:
Body + Extreme Wick
BASE CANDLE RULES
The BASE candle should preferably be:
Small relative to ATR
Small body relative to full candle range
Opposite candle before displacement
Or a small neutral base candle
Required settings:
ATR Length
Maximum Base Range x ATR
Maximum Base Body / Range
Accepted Base Candle Type
Accepted Base Candle Type options:
Opposite Candle Only
Opposite or Small Candle
Any Small Candle
DISPLACEMENT CONFIRMATION
Do not create a zone after a small move.
There must be a strong displacement.
Measure using:
Distance from base in ATR
Strongest impulse candle body
Directional candle ratio
Total departure distance
Required settings:
Bars After Base To Confirm
Minimum Departure x ATR
Minimum Impulse Body x ATR
Minimum Directional Candle Ratio
VALID ORDER BLOCK LOGIC
Do not mark every last opposite candle as an Order Block.
A valid Order Block must have:
Liquidity Event
Order Block Candle
Strong Displacement
Break of Structure
Fair Value Gap
Core model:
Liquidity Sweep -> OB Candle -> Displacement -> BOS -> FVG
BULLISH ORDER BLOCK
Bullish OB logic:
Price sweeps liquidity below a previous low or swing low
Then there is a bearish or base candle
Then strong bullish displacement
Then bullish BOS
Then bullish FVG
Only after these conditions should the candle become:
VALID BULLISH ORDER BLOCK
BEARISH ORDER BLOCK
Bearish OB logic:
Price sweeps liquidity above a previous high or swing high
Then there is a bullish or base candle
Then strong bearish displacement
Then bearish BOS
Then bearish FVG
Only after these conditions should the candle become:
VALID BEARISH ORDER BLOCK
LIQUIDITY SWEEP
Bullish setup:
Price sweeps below a previous Swing Low
Then reverses upward
Bearish setup:
Price sweeps above a previous Swing High
Then reverses downward
Required settings:
Liquidity Lookback
Liquidity Swing Length
Minimum Sweep Distance
Require Close Back Inside ON/OFF
BREAK OF STRUCTURE
Use meaningful market structure.
Do not count every small candle break.
Use Swing High and Swing Low.
Bullish BOS:
Close above previous valid Swing High
Bearish BOS:
Close below previous valid Swing Low
Required settings:
Structure Swing Length
BOS Confirmation
Options:
Close
Wick
Default:
Close
FAIR VALUE GAP
Use standard 3-candle FVG logic.
Bullish FVG:
Low of Candle 3 > High of Candle 1
Bearish FVG:
High of Candle 3 < Low of Candle 1
The FVG does not need to be inside the Order Block.
It must be created by the same displacement from the Order Block.
Required settings:
Minimum FVG Size
FVG Size Mode
Options:
ATR
Points
REACTION ZONE + ORDER BLOCK MERGING
This is very important.
If the same candle qualifies as both:
Reaction Zone
and
Valid Order Block
OR
If both zones overlap
OR
If both zones are very close
Then do NOT draw two zones.
Merge them into ONE zone.
Label:
OB + REACTION
Required setting:
Merge Distance x ATR
Suggested default:
0.10 to 0.20 ATR
COMBINED ZONE BOUNDARIES
Add setting:
Combined Zone Boundary Mode
Options:
Order Block Boundaries
Reaction Zone Boundaries
Union of Both
Recommended default:
Order Block Boundaries
ZONE INVALIDATION
The zone must NOT disappear after the first retest.
The zone should remain visible after multiple retests.
Default:
Keep Zone After Retests = TRUE
Demand zone invalidation:
Close below zone bottom minus buffer
Supply zone invalidation:
Close above zone top plus buffer
Required settings:
Zone Invalidation
Options:
Close
Wick
Default:
Close
Also:
Invalidation Buffer x ATR
Recommended:
0.05 to 0.10 ATR
RETESTS
Count retests but do not remove the zone because of a retest.
Possible display:
FRESH
R1
R2
R3
Retest display should be optional.
ZONE STRENGTH SCORE
Each zone should receive an internal score from 0 to 100.
This is NOT a guaranteed probability.
It is only a ranking score.
Score should consider:
Strength of displacement
Total departure in ATR
Strong impulse candle
Base candle quality
Base candle size
Liquidity Sweep
BOS quality
FVG presence
FVG size
Freshness
Number of retests
Distance price traveled away
Reaction only
Valid Order Block
OB + REACTION confluence
Suggested ranking:
OB + REACTION
higher than
Validated OB
higher than
Strong Reaction Zone
SCALPING MODE
The indicator is mainly for:
M1
M3
M5
M15
It must be sensitive enough to show useful scalping zones.
Do not make the conditions too strict.
Do not mark every minor candle either.
Optional presets:
Aggressive Scalping
Balanced Scalping
Strict
NUMBER OF ZONES
Do not limit the indicator to only one Demand zone and one Supply zone.
I want all valid important zones.
But do not fill the chart with low-quality zones.
Required settings:
Max Demand Zones
Max Supply Zones
Recommended default:
5 Demand
5 Supply
Allow up to:
10 to 15
If maximum zones are reached:
Remove the weakest zone
Do NOT simply remove the oldest zone
NEARBY ZONE FILTER
If two zones are very close:
Merge them
or
Keep only the stronger one
Do not draw duplicate or almost identical zones.
Required setting:
Merge Nearby Zones x ATR
DISPLAY
Demand Zone:
Green
Supply Zone:
Red
Valid Order Block:
Different shade or label OB
Combined Zone:
OB + REACTION
Possible label:
OB + REACTION 91 M5

FINAL LOGIC
Reaction Zone:
Small or Opposite BASE Candle
-> Strong Displacement
-> Reaction Zone
Bullish Valid Order Block:
Sell-Side Liquidity Sweep
-> Bearish/Base OB Candle
-> Bullish Displacement
-> Bullish BOS
-> Bullish FVG
-> Valid Bullish OB
Bearish Valid Order Block:
Buy-Side Liquidity Sweep
-> Bullish/Base OB Candle
-> Bearish Displacement
-> Bearish BOS
-> Bearish FVG
-> Valid Bearish OB
Highest Confluence:
Reaction Zone overlaps Valid Order Block
-> Merge into ONE zone
-> OB + REACTION

It must be created by the same displacement from the Order Block.
