Betting Modeling as Means of Developing "Market Intuition" The article dwells on the notion of "market intuition" and ways of developing it. The method described in the article is based on the modeling of financial betting in the form of a simple game.

A trend line is a linear function, y = mx + c, so with 2 trend lines you have 2 linear functions so all you need to do is solve the 2 equations when y and x are the same for both equations. First you need the m and c values for each line, c is the offset of each line at the same time coordinate, and m is the gradient/slope. Once you have your 2 equations you use substitution and you substitute for y in one equation by using the 2nd, e.g. y = 0.8x + 1.2 & y = 1.5x + 2.2 so 0.8x + 1.2 = 1.5x + 2.2 where the lines cross and solving this gives you x coordinate. Not sure what happens when you have a weekend in the mix . . .

WHRoeder:
thanks dear WHRoeder i will check it. 
Hello all.
it's me again :((
is anybody there to help me how can i calculate time and price of two crossed trend lines?
i have a code for it but it has some worng.
i want it be exact with any pips difference...
thank you
