// If previous bar opens in the lower 20% of its range and closes in the upper 20% of its range then sell on previous high+10pips.
// If previous bar opens in the upper 20% of its range and closes in the lower 20% of its range then buy on previous low-10pips.
// 
// Variation=1
// The previous bar is an inside bar that has a smaller range than the 3 bars before it.
