EURUSD +FTSE + Trigger line article

Firstly..here's a link to an educational article by Mircea Dologa. I brought his books some years ago and was both overwhelmed and underwhelmed by them. However here is a short article from the E-Signal learning base on 'Trigger Lines' and parallel trigger lines. I have been adding them to many forks over the last few months and have found them to have similar attributes to RL/WL/ML/s and can exert influence ( support/resistance) on price long after price has left the 'body' of the relevent fork.Some trigger lines in high time frame forks seem especially important and i have been tracking one in the E Mini Dow. charts to follow
