A chart pattern or price pattern is a pattern within a chart when prices are graphed. In stock and commodity markets trading, chart pattern studies play a large role during technical analysis. When data is plotted there is usually a pattern which naturally occurs and repeats over a period. Chart patterns are used as either reversal or ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
For example, the price of a share reaches a high of $30.00 on Wednesday, and opens at $31.20 on Thursday, falls down to $31.00 in the early hour, moves straight up again to $31.45, and no trading occurs in between $30.00 and $31.00 area. This no-trading zone appears on the chart as a gap.
Poems with a well-defined overall metric pattern often have a few lines that violate that pattern. A common variation is the inversion of a foot, which turns an iamb ("da-DUM") into a trochee ("DUM-da"). A second variation is a headless verse, which lacks the first syllable of the first foot.
The hikkake pattern, or hikkake, is a technical analysis pattern used for determining market turning-points and continuations. It is a simple pattern that can be observed in market price data, using traditional bar charts, point and figure charts, or Japanese candlestick charts.
Thus metric spaces together with metric maps form a category Met. Met is a subcategory of the category of metric spaces and Lipschitz functions. A map between metric spaces is an isometry if and only if it is a bijective metric map whose inverse is also a metric map. Thus the isomorphisms in Met are precisely the isometries.
The basic regularity theorem concerning the metric in harmonic coordinates is that if the components of the metric are in the Hölder space C k, α when expressed in some coordinate chart, regardless of the smoothness of the chart itself, then the transition function from that coordinate chart to any harmonic coordinate chart will be in the ...
