I'm Vasyl Lavrinenko. For more than 20 years I've been building trading systems for real investors, and my Expert Advisors have won awards at international trading competitions. On this channel I test trading ideas on real tick data and show what actually works, and what doesn't: backtesting without curve fitting, machine learning for trading in Python, MetaTrader 5 trading bots, forex risk management and position sizing. Every test uses real costs (spreads, commissions, swaps) and out-of-sample checks. No signals and no promises, just honest tests. 📚 Free courses with full code and data for subscribers of my Telegram channel Data Lab: https://t.me/lavrinenko_data Educational content only, not financial advice. Trading involves a risk of loss.
