Most people who try to trade fail not because they pick the wrong stock, but because nobody ever explained the vocabulary of markets to them in plain English. This first volume of the Must Know Trading Terms series fixes that.Across twenty-six short chapters, Personal Trading Coach walks you through the essential terms every trader needs before placing a single trade — what bid and ask really mean, how spreads work, what long and short positions actually do, why stop losses exist, how leverage multiplies gains and losses, and what trends, drawdowns, and risk-reward ratios are in practice.The approach is friend-to-friend rather than instructor-to-student. Each term gets a clear definition, a worked example, common mistakes to avoid, and a wider perspective. Visual diagrams accompany the most important concepts. No jargon for the sake of jargon, no false confidence, and no pressure to push you toward any broker or platform.By the end of this volume, you'll have a working vocabulary that puts you ahead of most people who try to trade. The five volumes that follow build on this foundation.For educational purposes only. Not financial advice.
