// --- Settings ---
DEFPARAM CumulateOrders = true
DEFPARAM PreloadBars = 10000

// --- Parameters ---
positionSize = 1          // contracts per trade
fractalPeriod = 113       // bars on each side of a confirmed swing close
longTrailPoints = 5       // trailing stop distance for longs (points)

channelPeriod = 20        // Donchian channel used as the protective stop
takeProfitPoints = 30     // profit target (points)

// --- Indicators ---
// A swing close is the extreme of the window centred on it, so it is only
// confirmed fractalPeriod bars later. The level holds until a new swing forms.
