TimeFrames 10/15/30/60...each time one of the timeframes gives a "signal at signal line" is an attempt to create/show structure forming out of random/chaos...a change in direction "should" come with more/better observable structure...30 minute is the most consistent; but 60 minute minute shows the most structure.
Moving averages is an artificial way to imagine structure...
Standard deviation is a statistcial way of searching for structure=statistics, deviation is a measure of difference for interval and ratio variables between the observed value and the mean. Standard deviation is the frequently used measure of dispersion: it uses squared deviations, and has desirable properties, but is not robust.
Average absolute deviation, sometimes called the "average deviation" is calculated using the absolute value of deviation – it is the sum of absolute values of the deviations divided by the number of observations.
Median absolute deviation is a robust statistic which uses the median, not the mean, of absolute deviations.
Maximum absolute deviation is a highly non-robust measure, which uses the maximum absolute deviation.
STRUCTURE...relative to...What???...(you do the math...before computers I drew my own charts and Bollinger Bands)
Weekly shows the most structure...or the least amount of randomness. 10 week chart=50day average... Stochastics will alway be the main indicator... Daily chart is next in showing the most structure... Then an overlay of daily randomly walking around for weeks=
