Expert Advisor EA MT4 Murray Maths Lines

Expert Advisor required to be built on MT4 Platform I have murray math lines, and i require that when the price moves down three murrey math lines, the system is then to: - Long 1 position, target 1 murrey math line Then as the trade keeps going AGAINST me, i continue to buy more - Long 2 Postions, Long 4 Postions, Long 8 Position etc etc. for each MM Line it goes against me Similarly if the price moves UP 3 murrey math lines, i will short one position, and continue to short as it goes against me This is the high level requirements, once i can get a grasp on the price, i can dig deeper into scope Keep in mind, i will need allot of variables, because i want to change things to test them For eg, instead of three MM line move, i may want to use a 1 MML move or 5 MML move or 0 MML move Also position sizing is the key here, so you need to understand what i am saying.
