ICT Order Blocks + Alerts
Order Block Identify & Verify
An educational Order Block (OB) indicator that finds ICT-style order blocks, confirms them with a volatility-filtered displacement candle, and tracks each level until price taps it or invalidates it. Every part of the chart is marked with a simple icon so you can learn to recognize order blocks on your own.
━━━ WHAT IS AN ORDER BLOCK? ━━━
An order block is the last opposite-direction candle before a strong move (displacement). Price often comes back to this level later, where it can act as support (bullish OB) or resistance (bearish OB).
━━━ HOW IT WORKS ━━━
Bullish OB (OB+)
• The OB candle is a down-close candle.
• The next candle is a strong up-close candle that closes ABOVE the OB candle's open.
• The OB level is the OB candle's open.
Bearish OB (OB-)
• The OB candle is an up-close candle.
• The next candle is a strong down-close candle that closes BELOW the OB candle's open.
• The OB level is the OB candle's open.
Displacement filter
The displacement candle's body must be larger than ATR × your multiplier. Because ATR adapts to the instrument and timeframe, weak, noisy moves are ignored and only real displacement counts.
Invalidation
An OB is invalidated when a candle CLOSES through its level. Wicks alone don't count.
• OB+ is invalid when price closes below the line.
• OB- is invalid when price closes above the line.
━━━ CHART LEGEND ━━━
▲ / ▼ = Order block candle
✓ = Displacement confirmed
─── = Active OB level
- - - = Invalidated OB level (when "Stop Line at Mitigation" is off)
OB+ = Bullish order block (possible support)
OB- = Bearish order block (possible resistance)
━━━ ALERTS ━━━
Turn each one on or off under Inputs → Alerts:
• New OB formed: when the displacement candle closes, with the OB level in the message
• Price taps OB level: the first time price returns to an active OB (once per OB)
• OB invalidated: when a candle closes through an active OB
To set one up: Create Alert → Condition: Order Block Identify & Verify → then choose
• "Any alert() function call" for every event you enabled, with the price level, or
• a single condition (New OB+, OB- Tapped, OB+ Invalidated, etc.).
Tip: use "Once Per Bar Close" for New OB and Invalidated alerts so they only fire on closed candles.
━━━ SETTINGS ━━━
Order Blocks
• Max Bullish / Bearish OBs: how many active OBs of each side to show.
Filters
• Min Displacement (ATR multiplier): how strong the displacement candle must be. 1.0 is balanced. Lower values give more OBs, higher values fewer but stronger ones. Timeframe suggestions are in the setting's tooltip.
• ATR Length: lookback for the ATR (default 14).
Visuals
• Colors, line width, show/hide markers, icon size.
Mitigation
• Stop Line at Mitigation: end the line when the OB is invalidated, or keep it extending as a dashed line.
• Keep Mitigated OBs (per side): how many invalidated OBs stay on the chart for reference.
━━━ HOW TO USE IT ━━━
• Use it to learn what valid order blocks look like: the ▲▼ candle, the ✓ displacement, and the level price may return to.
• Watch how price reacts when it taps an OB level. Does it hold or close through?
• Combine it with your own context (higher-timeframe trend, liquidity, session timing). An OB by itself is not a trade signal.
