Hi all,

I need help with the following as my mental arithmetic is terrible. Please help if you can. Here is the problem:

Presume the following...

A currency pair has an average daily range of 1800 points (180 pips)

At new day start (midnight broker time) price is exactly 1800 points from the top and bottom of the range.

Therefore the following is true:

Current top of this new daily average range is 1.63340 (1.6154 + 0.018)

Current bottom of new daily average range is 1.59740 (1.6154 - 0.018)

Price moves South towards 1.59740 by 200 points (20 pips), so the top of the range must also move South by 200 points.

The move South brings us 200 points closer to the bottom of the average range at a new distance of 1600 from the current price to the bottom of the range, whilst maintaining a distance of 1800 points from the current price of the day to the top of the average daily range.

If price moves North by 400 points from this point, we will be 200 points closer to the top of the range and exhausted 400 points of the daily range so far. The bottom of the daily range will now move 200 Points North. This will continue throughout the rest of the day, until the daily range has completed

How do I work out the ratio of the distance South:North? I used to know how to work this out as a kid but its been about 15 years since I did this stuff at school.

Any help would be greatly appreciated.
