Hi Simon. During your presentation, when speaking of Charts TA, Primary / Secondary Trends .. when looking at a share chart .. what do i use as my secondary chart and which as my primary? More importantly .. you spoke of Green line being above Red line etc.. when selecting 30 and 60 .. do i use 30 as green or 60 and select EMA, SMA or WMA?? .. what are the differences? Thanks!
Though both classified as primary colours, and share many other commonalities, red and green are entirely separate entities when put in the context of the physiological response of the eye to light.
Humans and other species with three types of color receptors are known as trichromats. These species respond to the light stimulus via a three-dimensional sensation, which can generally be modeled as a mixture of three primary colors. Protanopes and deuteranopes see no perceptible difference between red, orange, yellow, and green. All these colors that seem so different to the normal viewer appear to be the same color for this two percent of the population.
The colour green enjoys its highest intensity at a wavelength of 546.1(nm) while red is most intense at roughly 700nm (Though no real display device uses such primaries, as the extreme wavelengths used for violet and red result in a very low luminous efficiency.) Additive mixing of red and green light produces shades of yellow, orange, or brown.
