"...We place the air bag one tick above/below the high/low of the second bar back on one significantly higher time frame (or the next bar further back that has both a higher high and a higher low or a lower high and lower low).

The indicator calculates and shows Stop Loss levels (for Buy and Sell positions without installed SL) using this method.

Indicator variables:

int BAR = 200; // searching for in last BAR bar
int minSL = 25; // it is exposed when 2 bars are not found
bool show_bar = true; // show bars on which search for SL
show_info = true; // show active orders without SL
color color_BAR = DarkSlateGray; // colour bar on which search for SL
color color_Тек_BAR = Gray; // colour of the current bar
color color_SL = Gray; // colour of the marks
