but the trailing stop must be as per the time frame
for example
open any time frame, make calculations for last 500 bars by an ea to know the (high-low) to get the range for each bar / 500 = average range for each bar
then for this time frame, the trailing stop either the avg or little higher
for example
tf 5 min
500 bars
avg range 55.67 points
then my trailing stop is 60 or 70 points
