An (optional) include file to enhance error code handling experience.

The ZigZagExtremaOnArray is an mqh include file which contains the calculation function of MetaQuotes' Examples ZigZag, BUT you can use it on any buffer that contains curves or histograms, similarly to the MovingAverages.mqh from include. The idea was to get highs and lows of an indicator curve quickly with the help of an "onBuffer" function.

This EA demonstrates creating and saving a graphic chart using data from the MT5 Strategy Tester.

Four EAs writing to the same file, all with FILE_SHARE_READ|FILE_SHARE_WRITE, FileSeek(SEEK_END), FileWrite, FileClose. Looks correct. Every FileOpen returns success. No error in the log. And the lines vanish. Reason: FILE_SHARE_WRITE lets all four open at the same time. All four call FileSeek(SEEK_END) and get THE SAME offset, because none has written yet. All four write at the same position. Whoever closes last wins. Three lines vanish silently. In my case: 12 events expected, 8 in the file. The fix is to open EXCLUSIVELY (no FILE_SHARE_WRITE) and retry while another EA holds the file. And to shout in the log when the retries run out: a log that fails silently is worse than no log at all, because you trust it. The demo script reproduces both modes. To see the loss, drag it onto four charts at the same time with safe mode off and count the lines in the CSV. On a single chart the defect does not show up - which is why it passes in testing and breaks in production.

AttachExpert.mqh attaches an Expert Advisor to a chart from MQL5 code, with the inputs you choose and with "Allow Algo Trading" on or off.

Gaussian hidden Markov model fitted by Baum-Welch: regime probabilities without look-ahead, most likely path, expected durations and regime forecasts.
