The formula given in "Affine Geometry Of The Markets" by Viktor Likhovidov in this issue can be easily recreated in MetaStock 6.52 or higher. To create a formula in MetaStock, select Indicator Builder from the Tools menu, click New, enter the code for the formula, and then click OK. Repeat for the remaining formulas. A single formula can be used to plot the rising and falling transforms. It prompts you for two points on the trendline. For both points, you must input a date and a time. If you're working in an end-of-day chart, leave the time prompts at zero. You can also input a scaling factor to accentuate the curve ("slope scaling factor") and shift the result to prevent negative numbers ("display shift value"). | ||||||||
