If I may Share my view,
I believe every trader draws different lines.
I trade completely differently,
I noticed in the article it stated to give you an edge over other participants....I might be wrong , but I took this to mean an edge over other retail traders.
To me , it is not about other retail traders , it is the market movers that control the direction of the market.
Market movers I believe have one thing on their mind,they control where the market goes..they fill orders and get their liquidity,while making big profits along the way.
I try to watch and figure out where they are going and jump in and out on their coat tails so to speak.
I do not use lines....rather I look to the left of price continuously to see where the most probable filling orders will be.
Do not get me wrong ,I am not saying that drawing lines is not beneficial,I am just saying how I trade.
I believe , once again this is just my opinion, that it is better to have a chart that every one else is looking at , rather than seeing something that no one else sees.
The way I look to left is:
I load up fractals and use the attached indicator as a horizontal AussieBeau
