LRD Indicator

[hedgetrade321]

Hi,

need indikator for MT4 please help.

1) calculate the range (high-low) yesterday

2) today if a new high calculate lowerline=newhigh-range(yesterday)

if a new low, upperline=newlow+range(yesterday)

i have attached a pdf which describes the Methode

Buy if price touch the upperline or sell if price touch lowerline.

Thanks
