VORTEX INDICATOR

Posting a new Vortex Indicator. 'kingscorpion' has requested this indicator to be developed for marketscope, and short description was inserted here from his original request.

Information on this indicator can be found here:http://www.traders.com/Reprints/PDF_reprints/VFX_VORTEX.PDF

Vortex Indicator
by kingscorpion

Vortex, developed by Etienne Botes & Douglas Siepman of http://www.VortexFund.com, uses the relationship between today's high and yesterday's low for VM+ (similar to DMI+) and today's low and yesterday's high for VM- (similar to DMI-). The indicator plots only two line.

The first calculation is for the positive trending vortex movement VM+:
= ABS(Today's High - Yesterday's Low)

Next, calculate the negative trending vortex movement –VM. The formula is:
=ABS(Today's Low - Yesterday's High)

A 14-period sum of both VM+ and VM- is calculated.

Next, we calculate the true range (TR) and need to get the sum of the last 14 periods’ true range.

Finally, we need to calculate the ratio of each 14 period VM+ and 14 period VM- to the sum of the last 14 days’ daily true ranges.

And now the two ratios are drawn for the Vortex Indicator.

nicely done gentlemen, thank you!


In reference to heat maps, is it possible to create a Multi Currency Pair, MTF heatmap?

Thanks again for your efforts, nice work!

Can you please make the MTF_MCP_Vortex_List to display the actual values (in green for + or Red for -)? This will make it much more usefull to understand the strength of the Vortex.

Thank you in advance!
