This a simple (basic) strategy to exploit any swing HIGH & LOW occurring in the weekly TF.

This strategy may stay ONMARKET even more than 1 year!  Owing (or due ?) to high TP & SL there’s no advantage in backtesting it in tick-by-tick mode.

I suggest using the 2 or 4-hour TF as default to launch the strategy.

Experimenting is left to anyone to improve it.

TIMEFRAME (weekly, updateonclose)
//                      Swing High - Low
ONCE LookBack = 50                              //50   bars to make sure SWINGs have enough empty space to their left
ONCE MaxBars  = 2                               //2    bars to keep holding SWING valid
ONCE MaxHigh  = 0
ONCE MinLow   = 0
//    Swing HIGH
Hi =        high[1] = highest[LookBack](high)
Hi = Hi AND low[1]  = highest[3](low)
Hi = Hi AND close < open
//    Swing LOW
Lo =        high[1] = lowest[3](high)
Lo = Lo AND low[1]  = lowest[LookBack](low)
Lo = Lo AND close >= open
//
IF Hi OR Lo THEN
   MaxHigh = highest[3](high)
   MinLow  = lowest[3](low)
ENDIF
x = summation[MaxBars](Hi)
y = summation[MaxBars](Lo)
