Liquidity Internal Market Shift Strategy

This strategy detects internal market structure shifts that coincide with liquidity sweeps at recent highs or lows. A trade is opened when price touches a liquidity line and then shifts structure in the opposite direction. Trading can be limited to bullish or bearish setups only, or both.

Details

  • Entry Criteria:
    • Long: Price closes above prior bearish structure and has touched the recent low liquidity line.
    • Short: Price closes below prior bullish structure and has touched the recent high liquidity line.
  • Long/Short: Both directions or selectable Bullish Only / Bearish Only.
  • Exit Criteria:
    • Opposite signal after entry.
    • Stop-loss at StopLossPips pips.
    • Optional take-profit at TakeProfitPips pips.
  • Stops: Yes, configurable stop-loss and optional take-profit.
  • Filters:
    • Trades only within the specified time range.
    • Signal lock prevents repeated entries for several bars.
