Flow Control Oscillator (FCO)

The Flow Control Oscillator (FCO) is a momentum-based indicator that combines volume analysis and money flow to determine who is in control of the market—buyers or sellers—and how strong that control is. Unlike pure price-based oscillators, FCO integrates both price action and volume distribution to provide a more complete picture of market dynamics.

How It Works

Core Components:
Money Flow Index (MFI) -

• Scaled to -1 to +1 range
  
• Measures the flow of money into and out of an asset
  
• Identifies buying and selling pressure based on price and volume
  

Chaikin Money Flow (CMF) -

• Already in -1 to +1 range
  
• Measures the accumulation/distribution of volume
  
• Shows whether volume is accumulating (buying) or distributing (selling)
  

Combined Flow Control Line (FCO Line) -

• Equal-weighted composite of MFI and CMF
  
• Smoothed with SMA (default: 3 periods)
  
• Values above 0 = Buyers in control
  
• Values below 0 = Sellers in control
  

Signal Line -

• WMA of the FCO line (default: 6 periods)
  
• Used for timing entries and confirming momentum shifts
  

Momentum Histogram-

• Shows the rate of change in buyer/seller control
  
• Weighted by ADX (Average Directional Index) when enabled
  
• Larger bars = stronger momentum
  
• ADX weighting filters out choppy, unreliable signals
  

Key Zones
Neutral Zone (-0.3 to +0.3): Balanced market, low conviction
Healthy Trend Zone (±0.3 to ±0.7): Clear control without exhaustion
Warning Zone (±0.7 to ±1.0): Extended, approaching exhaustion
Extreme Zone (beyond ±1.0): Overbought/oversold, reversal likely

What To Look For

Reversal Setups:

• FCO in extreme zone (beyond ±1.0)
  
• FCO crosses Signal line in opposite direction
  
• Momentum histogram shrinking (weakening pressure)
  
• Interpretation: Buyers or sellers are exhausted and losing control
  

Trend Strength Setups:

• FCO crosses zero line (control shift)
  
• Momentum histogram growing in the same direction
  
• ADX confirms strong trend (no orange background)
  
• Signal line moving in same direction as FCO
  
• Interpretation: New control being established with building momentum
  

Divergences:

• Price makes new high/low but FCO doesn't confirm
  
• Indicates weakening momentum despite price movement
  
• Early warning of potential reversal
  

Choppy Market Warning:

• Orange background (ADX < 20)
  
• Small momentum bars regardless of FCO position
  
• Interpretation: Weak trend, avoid trading or use tight stops
  

Best Practices:

• Use with context: Combine with support/resistance levels (like VWAP) for confluence
  
• Multi-timeframe confirmation: Check higher timeframe FCO for overall bias
  
• Wait for confirmation: Let signals develop rather than predicting turns
  
• Respect extreme zones: Best reversal opportunities occur when FCO is beyond ±1.0
  
• Filter with ADX: Pay attention to background coloring—avoid choppy conditions
  

The indicator includes comprehensive alert conditions for:

• Reversal setups (extreme + cross + weakening momentum)
  
• Trend strength signals (zero cross + growing momentum + strong ADX)
  
• FCO/Signal crossovers
  
• Extreme overbought/oversold conditions
  
• Control shifts (buyers/sellers taking control)

New Features:

Component Weighting Options:

• Added flexible weighting between MFI and CMF components
  
• Equal (default) - 50/50 split, matches original behavior
  
• MFI Heavy - 70/30 focus on money flow
  
• CMF Heavy - 30/70 focus on volume distribution
  
• Custom - Manual slider control from 0.0 to 1.0 for precise tuning
  

Enhanced Smoothing Options:

• TEMA (Triple Exponential Moving Average) - Ultra-responsive with minimal lag
  
• DEMA (Double Exponential Moving Average) - Smooth but reactive
  
• VWMA (Volume Weighted Moving Average) - Incorporates volume into smoothing
  
• Added to both FCO line and Signal line options
  

Improvements:

• Reorganized input groups for better clarity
  
• Increased FCO Smoothing Length max to 20 for more flexibility
  
• Added tooltips for custom weighting explanation
  

Note: All default settings remain unchanged. Existing users will see the same indicator behavior unless they adjust the new weighting and smoothing options.
