# Mathematical proportion and range is the last high- the last low

"if all highs and lows in the market are exact proportions of previous ranges."

then can you write the statement;

$$x = \frac{a}{b}\times{range}$$

where x is a high, a/b is a mathematical proportion and range is the last high- the last low

Is that correct? if not, what would be?

Thanks
