Added a small new function "slopechangelvl1", if true, will do slope alerts only when above or below level1 which is useful if you use it with all currencies on.

I would also like to ask pro coders here if they could add another useful thing: rate of change from (bar-X), x being a variable (default 1). It could be shown on the display as USD 0.007843 + 0.15 (normalized). Could be green or red depending on if the number is positive or negative. It would serve as sort of momentum, helping to pair currencies more effectively.

There are other features which could be coded in (like varying thickness of line depending on value or counting the crosses over certain number of bars and show the pair with least crosses) but it is unfortunately all beyond my skills.
