Read The Signal.
Know The Limits.
Practical guides for reading market data, understanding portfolio numbers and making a research process you can explain. Start with the method; keep its assumptions in view.
Original Guides
05 FIELD NOTESA Price Needs A Timestamp And A Source
Learn to distinguish a recent fetch from a recent market event, compare feeds fairly, and recognize when a displayed quote cannot support an execution decision.
Know What Your Profit And Loss Measures
Work through cost basis, realized and unrealized results, then identify the cash flows and assumptions that stop a simple percentage from being a complete performance record.
Turn A Watchlist Into A Research Process
Build a small, evidence-led review routine that separates a ticker worth studying from a position, a thesis from a fact, and a useful source from a repeated headline.
Paper Results Do Not Establish Live Execution
Use simulation to study a process while keeping its assumptions separate from a broker's real fills, pending orders, buying power and loss exposure.
Research Domains And Predictions Without False Precision
Use an evidence checklist for domain costs and event definitions, while separating a research estimate from a verified valuation, a probability claim or an executable trade.
Make The Method Visible.
These guides explain the questions behind the interface: where a quote came from, what a percentage divides by, and which assumptions a simulation leaves out. They use hypothetical examples and link to primary references so you can inspect the reasoning.
They are educational material, not personalized advice or a recommendation to buy, sell or hold an asset. Figures do not represent actual account performance. If a method or app description needs correction, send the guide title and the issue through Contact.
