Traders Dynamic Index (TDI) – FX Replay Guide

The TDI Indicator in FX Replay combines momentum (RSI) and trend-following (MA) logic into one streamlined oscillator. It helps you identify entry/exit signals, trend bias, and momentum shifts in real time during backtesting and replay.

How to Add It:

• Open your chart in FX Replay
• Click the Indicators button
• Search for “TDI” or “Traders Dynamic Index”
• Apply it, and customize your settings (e.g., RSI length, smoothing period) as needed

What the Lines Mean:

• Green Line (RSI Price Line): Fast momentum tracker
• Red Line (Signal Line): Smoother RSI average — helps confirm direction
• Yellow Line (Market Base Line): Overall trend filter
• Optional Bands: Show volatility zones — extremes can indicate overbought/oversold conditions

Entry/Exit Logic:

Buy Setup:

• Green crosses above red (signal line), ideally above yellow (base line)
• Confirm with bullish candle or structure break

Sell Setup:

• Green crosses below red, especially below yellow line
• Use price action or liquidity zone rejection as confirmation

Backtesting in FX Replay:

• Focus testing around session opens (London/NY) for high-probability setups
• Example rule:
  “Only long if green > red and yellow is sloping up”
• Journal results by signal type:
  • Cross
  • Divergence
  • Exit on base-line flip

Pro Tips:

• Use volatility bands as dynamic overbought/oversold filters
• Combine TDI with:
  • Supertrend for trend confirmation
  • SMMA for structure alignment
  • Liquidity sweep zones for precise entries

Strategy Use Case:

• Enter trades based on TDI crossovers, filtered by yellow line direction
• Exit when green crosses back over red, or when price invalidates the setup (e.g., break of previous low/high)
• Tune RSI settings to match your timeframe:
  • Use 13 for swing trading
  • Use 7 for scalping
