Recently i improve my trading skill by using Tread Lines.
By adding this skill i able to :
a. Know where the price will end. (Best for TP)
b. Know whether this is a good entry.
c. Know the trend of the current market.
d. Filter some lousy entry.
How to draw a TL?
My recommendation is minimum connect 3 area. Show below.

As can see the round blue show that 3 area of resistance. Base on this single TL we able to filter, get out at the best point and going in the correct trend.
If you can master the TL, ur trading skill is higher one level. TL is another big topic to understand so u should pay attention on it. It can save ur acc from being burn and help u to see the future of the market. It is like a crystal ball for us fx trader.
I just show a small bite of the power of TL. Knowing TL is 1 thing how to apply it is another thing.
Hope it help.
