FORECAST ™ is looking like the direction of the market in the history of the financial instrument and compares with the current. The principle of operation. Taking the specified interval (default is 24 bar), we move into the past by comparing the sequence with the sequences LWMA LWMA sample. The comparison is performed by Spearman and, further, adjustment of the sample (default height difference should not exceed 10%). After accumulating the required number of the most similar samples (default 5), we project the price movement, which took place in history after all samples found at the moment. Real bars superimposed on each other to form a corridor of possible price movements.
The corridor of possible price movements drawn with brown stripes (the cloud). Cloud on the screenshot is not specified, it is derived, if found at least two similar sample. Blue bars inside the cloud - one of the options price behavior.
Brown Line "beginning of the sample" and "end of the sample" can be freely moved (previously allocated by double-clicking). Recalculation of the forecast will be made within 1-2 seconds after you move the lines. The beginning and end can be fixed to the sample is not moved after the new emerging bars (then the forecast will be fixed and will not be redrawn with each new bar). Alternatively, you can lock only the beginning of the sample, such as early in the day (as in the screenshot), and the end of the sample is moved after the new bars. In this approach, each bar will be slightly refine the forecast (the sample size is increased, but the beginning of the sample is fixed).
For a reliable indicator of prognosis need history pair. If the story does not disappoint, the indicator will know about it. If similar patterns of behavior in the story will be found a little indicator advises to weaken the rigor of comparison, reducing the value ScalePercents. It should be remembered, however, that the prediction then becomes less reliable.
