Using reward-to-risk without fooling yourself

How to use these guides

The three guides map to the order you actually use a ratio in. Start with how to read one — a number is not a verdict, and the guide says what turns it into one. Then size the trade, because a ratio with no position size attached is a plan you cannot place. Finally, the mistakes list is the screen that catches the ways a clean ratio misleads — a stop placed for comfort, a target stretched to flatter the maths, a win rate quoted with no ratio.

None of them assume you take the recommendation here on trust. Each is built so you could apply it to any source and reach your own verdict; the guide simply argues that one source comes out intact. Where a guide refers to a specific test — the grade, the lock, the record — it links through to the matching scorecard criterion so you can go as deep as you want.

What these guides deliberately do not do

They do not rank a long list of services by stars and they do not chase the latest “best ratio” trend. Both reward whoever markets hardest, which is the opposite of what a trader needs. Instead each guide hands you a check you can run, because a method you apply yourself outlives any ranking that goes stale the week after it is published. A source that tops a list today can quietly widen a stop on a losing trade tomorrow; a source whose levels are timestamped before their outcome cannot. The guides are written around that durable difference.

The mistake these guides are meant to prevent

The most expensive error a trader makes with reward-to-risk is treating the ratio as the decision. A 5:1 ratio on a trade you win one time in ten is a losing strategy; a 1:1 on a trade you win three times in four is a good one. The ratio is half of an equation whose other half is the win rate, and the calculator shows both for exactly that reason. Each guide here is structured to move you from admiring a ratio to interrogating it — from “that looks like a great trade” to “at that ratio, do I win often enough to make it pay?” That shift is the whole value of the cluster.
