GuideWhere to Set a Stop-Loss and a Take-ProfitThe stop goes where your idea is wrong, not where your comfort runs out — and then the position size adapts to it. Here is the volatility argument, the sizing arithmetic, and the win rate each reward multiple demands.ExplainerRisk/Reward Ratio Explained: The Win Rate Each Ratio RequiresA 1:3 ratio does not make you right more often — it lets you be wrong three times out of four and still break even. Here is the inversion, a table of ratio against required win rate, and what costs do to both.GuidePosition Sizing: What the 1 Percent Rule Actually ConstrainsThe rule caps the loss, not the position. Here is the formula, a worked example, and what a run of ten losses costs at 1 percent versus 2 percent.How-toHow to Calculate Your Liquidation Price on a Leveraged PositionThe liquidation price follows directly from your leverage: at 10x a 10 percent move wipes you out. Here is the formula, the maintenance margin that moves it closer, and how to read the number before you open.ExplainerDividend Reinvestment: What Actually Drives the DifferenceReinvesting a 3 percent yield for 30 years turns 100 shares into 242.7 and multiplies the final position by exactly that factor: $32,434 becomes $78,726. Tax at 30 percent on each dividend costs $18,223 of it — nearly two and a half times the tax actually paid.ExplainerAveraging Down Halves the Loss and Doubles the PositionTen shares at 100 plus twenty at 80 gives an average of 86.67. Buy forty at 50 instead and it falls to 60 — but the money at risk goes from 2,600 to 3,000.
