S7 Up Bot Strategy

Breakout system that looks for nearly equal highs or lows followed by a sharp price move. When two consecutive lows are almost equal and price rises by Span Price, the bot enters long. It enters short when two highs align and price drops by Span Price. Positions are protected with optional take-profit, stop-loss, trailing stop and early exit features.

Details

  • Entry Criteria:
    • Buy: Difference between current and previous low is below HL Divergence and price is Span Price above the low.
    • Sell: Difference between current and previous high is below HL Divergence and price is Span Price below the high.
  • Long/Short: Both.
  • Exit Criteria:
    • Take profit or stop loss.
    • Trailing stop or zero trailing adjustment.
    • Early exit if price crosses previous high/low (Exit At Extremum) or nears reversal level (Exit At Reversal).
  • Stops: Absolute take-profit and stop-loss with optional trailing.
  • Filters: None.

Parameters

  • Take Profit – profit target in price units.
  • Stop Loss – loss limit in price units, 0 for automatic extreme based stop.
  • HL Divergence – maximum allowed difference between two consecutive highs or lows.
  • Span Price – distance from extreme to price required for entry.
  • Max Trades – maximum simultaneous trades.
  • Use Trailing Stop – enable trailing stop mechanism.
  • Trail Stop – trailing stop distance.
  • Zero Trailing – move stop toward price once position is profitable.
  • Step Trailing – minimal step to adjust zero trailing.
  • Exit At Extremum – close if price crosses previous high/low.
  • Exit At Reversal – close if price approaches opposite extreme.
  • Span To Revers – distance from extreme to trigger reversal exit.
  • Candle Type – timeframe used for analysis.
  • Order Volume – quantity per trade.
