OB + Big Trades Signal
# OB + Big Trades Signal Indicator
## Overview
The **OB + Big Trades Signal** indicator combines three powerful concepts into a single, clean signal layer: **Volume-based Order Blocks**, a **Big Trades (Whale) Detector**, and a **Daily VWAP filter**. A signal is only generated when all three conditions align — significantly reducing noise and increasing the quality of each entry.
---
## How It Works
### 1. Order Blocks with Volume
Order Blocks are price zones where a consolidation phase was followed by a strong breakout candle with above-average volume. These zones represent areas where institutional participants placed significant orders, and price tends to react when revisiting them.
- **Bullish Order Block** — forms when a consolidation is broken to the upside with high volume. Marks potential support / demand zones.
- **Bearish Order Block** — forms when a consolidation is broken to the downside with high volume. Marks potential resistance / supply zones.
Order Blocks are automatically removed ("mitigated") when price trades through them, keeping the chart clean and relevant.
### 2. Big Trades Detector
The Big Trades component analyzes intrabar volume intensity using a statistical model. It splits each candle's volume into estimated **buy pressure** and **sell pressure** based on the candle's close position within its range. A trade is classified as a "Big Trade" when its volume deviates significantly from the recent average — specifically beyond a configurable multiple of the standard deviation (sigma).
- **Big Buy** — abnormally high buying pressure on the current bar
- **Big Sell** — abnormally high selling pressure on the current bar
Three tiers of intensity are detected (T1, T2, T3), with T3 representing the most extreme whale activity.
### 3. Daily VWAP Filter
The Volume Weighted Average Price (VWAP) resets every day at 00:00 UTC. It acts as a directional bias filter:
- Price **above** VWAP → bullish bias → only Long signals are allowed
- Price **below** VWAP → bearish bias → only Short signals are allowed

## Signal Logic
| Signal | Conditions Required |
|--------|-------------------|
| **LONG** | Big Buy detected + Price near/inside a Bullish Order Block + Price above Daily VWAP |
| **SHORT** | Big Sell detected + Price near/inside a Bearish Order Block + Price below Daily VWAP |
All three conditions must be true simultaneously for a signal to appear.

### Big Trades Detector
| Parameter | Description |
|-----------|-------------|

| Sensitivity (Sigma) | Standard deviation multiplier — higher = fewer but more extreme signals |
### VWAP & Display
| Parameter | Description |
|-----------|-------------|
| Show Daily VWAP | Toggle VWAP line visibility |
| VWAP Color | Color of the VWAP line |
| Show Order Blocks | Toggle Order Block boxes on/off |
### Signal Labels
| Parameter | Description |
|-----------|-------------|

| Label Size | Tiny / Small / Normal / Large / Huge |
| Background Highlight | Tints the bar background when a signal fires |
### Alert Options
| Parameter | Description |
|-----------|-------------|
| Signal Direction | Filter alerts to Long + Short, Only Long, or Only Short |
| Push Notification | Sends a push alert via `alert()` directly — no manual alert setup needed |
| Enable Time Window | Restricts alerts to a defined time range |
| From / To Hour & Minute (UTC) | Start and end of the active alert window in UTC |
> **Time zone note:** The time window runs in UTC. Adjust for your local time zone when setting the hours (e.g. CET = UTC+1, so subtract 1 hour).

## Alerts Available
The indicator provides **9 alert conditions** selectable in the TradingView alert dialog:
1. `LONG – OB + Big Buy + VWAP` — Full Long signal (all filters active)
2. `SHORT – OB + Big Sell + VWAP` — Full Short signal (all filters active)
3. `Signal (Long or Short)` — Either direction
4. `Big Buy detected (unfiltered)` — Big Buy only, no OB/VWAP filter
5. `Big Sell detected (unfiltered)` — Big Sell only, no OB/VWAP filter
6. `Price in Bullish OB Zone (above VWAP)` — Price enters demand zone
7. `Price in Bearish OB Zone (below VWAP)` — Price enters supply zone
8. `Price crosses VWAP upward` — Bullish VWAP crossover
9. `Price crosses VWAP downward` — Bearish VWAP crossover
All signal alerts include an **anti-spam filter** — each alert fires only once per bar regardless of how many ticks meet the condition.

## Tips & Recommendations
- **Timeframe:** Works best on 5m–1h charts. Lower timeframes produce more signals; higher timeframes produce fewer but more significant ones.
- **Sensitivity tuning:** Start with Sigma = 3.0. Increase to 3.5–4.0 for stricter, less frequent signals. Decrease to 2.0–2.5 for more activity.
- **OB Proximity:** Set tighter (0.05–0.10%) for precise entries, wider (0.20–0.30%) if you want signals slightly ahead of the zone.
- **Push alerts:** Enable the Push Notification toggle and set your time window to only receive alerts during your active trading hours — no noise outside your session.
- **Combine with trend context:** For best results, trade Long signals during uptrends and Short signals during downtrends on a higher timeframe.
