Writing a Trade Thesis in Three Sentences

A trade without a stated reason is a gamble with a chart attached. A short written thesis forces clarity and makes later review meaningful.

Three sentences are enough. The first states the context and the reason: what is the market doing, and what is the setup? For example: the daily trend is up, and price is pulling back to a prior support zone that held twice. The second states the trigger and the plan: I will buy on a bullish rejection candle on the four-hour chart, with the stop below the zone and the target at the previous high. The third states the invalidation and the risk: if price closes below the zone, the idea is wrong, and I will lose 1 percent.

Notice what the thesis contains. A reason grounded in observable facts. A specific trigger. A defined point of being wrong. It does not contain predictions with certainty or emotional language.

Write it before entering, and save it with the screenshot. After the trade closes, compare the outcome with the thesis. Was the reasoning sound, even if the result was a loss? Did the market behave as described?

A pattern of weak or missing theses correlates with impulsive trades. A pattern of strong theses and losses suggests that variance or strategy quality should be examined, not discipline.

Keep it brief enough to do every time.

Practical step: write a three-sentence thesis for your next trade before placing the order.

The third sentence is the important one. If you can't say where the idea is wrong, you don't have a trade yet, just an opinion about the chart. Make it a price and a condition, not a feeling. For example, the idea is wrong if price closes on the 4 hour chart below the support zone at 1.2650, because then the level has failed. Your stop then goes a bit beyond that, giving room for spread and wicks. If the stop that the thesis requires is too far for your normal risk, the answer is a smaller position or no trade, not a tighter stop that sits inside the noise.

Reading old theses on losing trades is oddly reassuring. When the reasoning was sound and the trade still lost, that's variance, and it's good to see it written down. It also helps separate the two kinds of loss. A good thesis that lost is fine and needs no change. A thesis that ignored something obvious, like a Fed decision at 7pm Lagos that evening, or a support zone that had already broken twice, is a process error you can fix. I mark each losing trade A or B in the journal for exactly that reason. Over a few months, the ratio of A to B losses says more about progress than the P&L.

Three sentences is a good length. One practical tip: write the thesis before entering, and review it at the end of the trade. Comparing the actual outcome with the written invalidation shows whether the trade was exited for the right reason, which is useful even when the trade was profitable.

Keeping the theses in the journal also makes it possible to review them in bulk later and see which types of reasoning work best.

For a scalper the three sentences have to be written before the session, not before each trade. At M5 speed there is no time to compose a thesis between the trigger candle closing and the entry, so the useful version is a prewritten card per level, with the trade itself only adding a time stamp.

I would add a time limit to the third sentence. An idea that was meant to work in the London open is wrong in a different way if it is still flat at 10:30 GMT, and naming that clock time stops a dead trade from drifting into the US session.

Fairman's A and B grading gets sharper if it is done blind. Cover the outcome column, grade the thesis on its own, then reveal the result, because graders who see the P&L first tend to call losing theses weak and winning ones sound.

A quick quality test is counting hedging words. If sentence two needs maybe, probably or might, the trigger is not defined yet.

Does anyone keep a short set of reusable thesis templates for each setup? Or is each one written fresh?

Fairman's 1.2650 example hides a small conflict between the close condition and the stop. If the idea is wrong on a 4 hour close below 1.2650 and the stop sits at 1.2635, a candle can close at 1.2642 with the stop untouched.

At that point the thesis says the trade is dead while the order says it is still alive. The third sentence should state which one wins, otherwise the trader ends up holding a broken idea because the stop has not been hit.

Letting the close rule win, with the stop kept for the fast move, tends to be the cleaner choice. With entry at 1.2660 the stop is 25 pips away, so exiting at 1.2642 instead of 1.2635 saves 7 pips, or 0.28R each time it happens.

A second check is whether a winning trade still matched the thesis. If price reached the target only after first closing below the zone, the result was positive but the reasoning failed, and that trade deserves a review as a process miss.

Those right for the wrong reason trades are the most likely to build false confidence in a setup. They also tend to repeat, since nothing in the result tells anyone to look.
