Vasyl Lavrinenko (PegasMaster) has been developing and testing automated trading systems for twenty years. In 2007 his expert advisor Pegas took third place worldwide in the MetaQuotes Automated Trading Championship, where he is listed as Vasiliy Lavrinenko. Since then he has tested fourteen families of trading ideas and kept the trade-by-trade record of each, the failures included. His courses are built from that record: every number shown names the file it comes from, and most of what you see is ideas that did not survive the checks. He teaches the checks, not strategies, because a procedure that removes wrong ideas early is the part he found worth passing on.
