Order-Flow Market StructureOrder-Flow Market Structure by The_Forex_Steward
A precision tool for visualizing internal shifts, swing structure, BOS events, Fibonacci levels, and multi-timeframe alerts.
What It Does
The Order-Flow Market Structure indicator intelligently tracks and visualizes price structure using higher timeframe candles. It automatically detects:
• Internal bullish and bearish structure shifts
• Swing highs and lows (HH, HL, LH, LL)
• Break of Structure (BoS) confirmations
• Fibonacci retracement levels from recent swing moves
• Real-time alerts across LTF, MTF, and HTF modes
It’s a complete tool for traders who follow Smart Money Concepts, ICT, or institutional price action strategies.
How It Works
• You select a Higher Timeframe (HTF) to set the structural context
• Internal shifts are identified using HTF candle closes
• The indicator scans for swing highs/lows after each internal shift
• Breaks of previous swing points confirm BoS and plot horizontal lines
• Zigzag lines visually connect structural points (swings and BoS)
• Fibonacci levels are drawn between the latest swings
• Alerts can be configured for structure shifts, BoS events, and fib level breaks
How to Use It
Set your preferred HTF (e.g., 1H while trading on 5-minute)
Enable Fibonacci levels to visualize retracement zones
Watch for:
• Bullish internal shifts → HL to HH
• Bearish internal shifts → LH to LL
• BOS → Breakout confirmation
Enable alerts to catch structural events in real-time
Adjust the "Safe History Offset" if working with long lookbacks or volatile assets
Who It's For
• Traders using Smart Money, ICT, or market structure-based systems
• Scalpers, day traders, and swing traders
• Anyone needing precise structural insight across multiple timeframes
Features
• BoS detection with custom line styles and width
• HH, HL, LH, LL label plotting
• Optional Fibonacci retracement zones
• Custom alerts for swing shifts and fib level breaks
• LTF, MTF, and HTF alert modes
Stay aligned with structure, trade with precision, and get alerted to key shifts in real time.

RSI, CCI, ADX Panel (Custom TF for Each)RSI, CCI, and ADX Combined – Multi-Timeframe, Fully Customizable Panel Indicator for TradingView
Overview
This Pine Script indicator integrates the Relative Strength Index (RSI), Commodity Channel Index (CCI), and Average Directional Index (ADX) into a single, clean panel for effortless technical analysis. Each indicator operates independently, with customizable length, smoothing, and time frame for maximum flexibility. Traders can now monitor momentum, trend strength, and overbought/oversold conditions across different time frames—all in one place.
Key Features
Independent Controls: Set length, smoothing (ADX), and time frame individually for each indicator via the settings panel.
Multi-Timeframe Support: Each oscillator (RSI, CCI, ADX) can be calculated on its own time frame, enabling nuanced inter-timeframe analysis.
Customizable Visualization: Adjust line color and thickness for each indicator to match your chart style.
Clean, Non-Overlay Display: All three indicators are plotted in a dedicated panel beneath the price chart, reducing clutter.
Reference Levels: Includes standard reference lines for oversold/overbought (RSI, CCI) and trend threshold (ADX) for quick visual cues.
Usage Ideas
Swing Trading: Compare short- and long-term momentum using different time frames for RSI, CCI, and ADX.
Trend Confirmation: Use ADX to filter RSI and CCI signals—only trade overbought/oversold conditions during strong trends.
Divergence Hunting: Spot divergences between time frames for early reversal signals.
Scalping: Set RSI and CCI to lower time frames for entry, while monitoring higher timeframe ADX for trend context.
How to Install
Paste the script into the Pine Editor on TradingView.

RSI + TSV Kombi📊 RSI + TSV Combo Indicator (Intraday Reversal Tool)
This custom TradingView indicator is designed for intraday traders who want to combine price momentum (via RSI) with volume-based confirmation (via TSV). It’s particularly powerful for spotting short-term reversals around key market zones like VWAP, support/resistance, or options levels.
🧠 What does the Indicator show?
The indicator contains two elements in one pane:
🔹 Top Line – RSI (Relative Strength Index)
Type: RSI(7) – a short-term version of the classic RSI
Color-coded:
🟢 Green when RSI < 30 → potential oversold → bullish bias
🔴 Red when RSI > 70 → potential overbought → bearish bias
⚪ Gray in between → neutral
🔎 Purpose: Identifies overextended price moves — early warning for possible reversal zones.
🔸 Bottom Bars – TSV (Time Segmented Volume)
Formula: EMA(change(close) * volume, 9)
Color-coded histogram:
🟢 Green when TSV > 0 → bullish volume momentum
🔴 Red when TSV < 0 → bearish volume momentum
🔎 Purpose: Confirms whether price moves are supported by actual volume — helps filter false signals from RSI.
⚖️ How to Interpret the Indicator
✅ Long Setup
RSI is below 30 (green line)
TSV bars turn green or cross above 0
Ideally at a support level or near VWAP
➡️ Buy signal confirmed by volume
❌ Short Setup
RSI above 70 (red line)
TSV bars are red or turning red
Ideally at a resistance zone or VWAP deviation
➡️ Sell signal confirmed by selling pressure
⚠️ Avoid trades when...
RSI is oversold/overbought, but TSV disagrees
(e.g. RSI < 30 but TSV is red → weak confirmation)
🧭 Practical Usage in Intraday Trading (e.g. 5-minute chart)
Step What to look for
Setup Zone RSI hits extreme level (under 30 or above 70)
Volume Confirmation TSV bars flip color (red → green or vice versa)
Entry Price breaks candle high/low with volume support
Exit VWAP, volume node, or next support/resistance zone
🔧 Options for Expansion
This script is already running cleanly, but you could easily extend it with:
📍 Buy/Sell Arrows on chart when both RSI + TSV align
🔔 Alerts for instant trade triggers
💡 Overlay version that places symbols directly on the price chart
🔒 Filter to only show signals above/below VWAP
Let me know — I can build any of these for you.
✅ Summary
This RSI + TSV Combo is a simple yet powerful tool to:
Spot momentum reversals
Confirm trades with volume
Stay disciplined and rule-based in fast-moving intraday setups
It’s especially useful when combined with:
VWAP
Volume Profile Zones (HVNs/LVNs)
Key psychological or options levels
ATR HUDThis script displays the Average True Range value for your chart's timeframe and displays it in a small tidy table. ATR is a valuable indicator for position sizing, stop placement, profit expectancy and other trade planning considerations. With this script you can keep the current ATR value visible without taking up much precious window space. You can select your preferred smoothing method, lookback period, and window position in the settings. Enjoy!

FSTO + MACD Combined OscillatorFSTO + MACD Combined Oscillator with Advanced Alerts
Introduction
The FSTO + MACD Combined Oscillator is a powerful technical analysis tool that synergizes two proven momentum indicators to deliver high-confidence trading signals. By combining the Moving Average Convergence Divergence (MACD) with the Fast Slow Trend Oscillator (FSTO), this indicator provides unique insights into market momentum, trend direction, and potential reversal points.
Key Features
1. Dual Indicator Integration
MACD Component:
Fast EMA (user-configurable period)
Slow EMA (user-configurable period)
Signal line with customizable smoothing
Histogram showing momentum strength
FSTO Component:
Short-term EMA (price-based)
Long-term EMA (price-based)
Signal line with adjustable period
Zero-line crossover detection
2. Advanced Alert System
Four specialized alert conditions that trigger only when both indicators confirm momentum shifts:
Bullish Reversal Alert
FSTO crosses above zero + MACD transitions from falling to rising
Strong trend reversal signal
Bullish Momentum Alert
FSTO crosses above signal line + MACD transitions from falling to rising
Confirmation of bullish momentum
Bearish Reversal Alert
FSTO crosses below zero + MACD transitions from rising to falling
Strong trend reversal signal
Bearish Momentum Alert
FSTO crosses below signal line + MACD transitions from rising to falling
Confirmation of bearish momentum
3. Visual Indicators
Color-coded plots:
MACD line (blue)
MACD signal line (orange)
FSTO line (purple)
FSTO signal line (amber)
Histogram:

How It Works
The indicator calculates two parallel momentum measurements:
MACD = EMA(close, fast_length) - EMA(close, slow_length)
FSTO = EMA(close, short_period) - EMA(close, long_period)
The true power emerges when these indicators confirm each other's signals:
MACD detects momentum shifts in price derivatives
FSTO identifies trend changes in price itself
Combined signals filter out false positives
Trading Applications
1. Trend Identification
Bullish Trend: FSTO > 0 and MACD > signal line
Bearish Trend: FSTO < 0 and MACD < signal line
2. High-Probability Entries
Long Entry: Alert 1 or 2 triggers
Short Entry: Alert 3 or 4 triggers
3. Exit Signals
MACD histogram color change (green to light green)
FSTO crossing signal line against trend direction
4. Risk Management
