How to choose your style and stop changing it every week
The choice comes down to three numbers known in advance. Verifying that choice takes a sample — and the longer your horizon, the longer you will not know whether it works.
Three questions to answer honestly
First: how many hours a day will you really watch a chart — not in an ideal week but in an ordinary one, with work and errands. Second: what is your account size and your fees — that decides what a round trip costs and whether any headroom remains on a short horizon. Third: how long can you stand not intervening. All three answers are numbers, and all three are known before the first trade. A style is not chosen, it is computed from these three answers; only then do you pick a markup method.
What each style demands
| Style | Hours a day | What is critical | Main cost |
|---|---|---|---|
| Scalping | hours, whole session | limit entries and liquidity | fees |
| Day trading | 1–3 hours | discipline of closing by evening | fees |
| Swing | 20 minutes | sitting through the night without looking | funding |
| Position | an hour a week | the shelf life of the idea | months of funding |
How long until you know whether the choice works
Here comes the main inconvenience nobody mentions. You can only tell whether an approach works from a sample — thirty to fifty trades, because on anything smaller the result is fully explained by luck. And that sample accumulates at very different speeds. A scalper with thirty trades a day gets fifty in two days. A day trader with three gets there in two and a half weeks. A swing trader with three a week needs four months. A position trader with three a month needs nearly a year and a half.
When you get the answer
| Style | Trades | 50 trades take |
|---|---|---|
| Scalping | 30 a day | 2 days |
| Day trading | 3 a day | 17 days |
| Swing | 3 a week | 4 months |
| Position | 3 a month | nearly a year and a half |
This table implies something that inverts the usual reasoning. A long horizon is cheaper in costs but more expensive in verification time: you will discover a flaw in the approach after a year rather than after a week. A short horizon gives fast feedback but charges fees for it. That is the real trade-off between styles — not fast versus slow, but cheap versus finding out the truth quickly.
Changing style after a losing streak
Five losses in a row happen regularly even to a working approach — that is covered in the risk course. But when a streak arrives, the temptation to change not the parameters but the horizon itself becomes almost irresistible: swing is not working, let me try intraday. At that moment the sample resets to zero. You start counting the first trade of the new style, and a month later, when the next streak comes, you repeat the manoeuvre. Someone who changes style every few weeks accumulates a sample in NONE of them within a year and therefore knows nothing about himself except the balance.
How to change style when the decision is genuinely right
Changing horizon can be justified: circumstances changed, screen time appeared or vanished. The correct order is this. First close every position of the old style — do not carry them into the new one, because their size was computed for a different stop. Then recompute position size for the new horizon: the stop changes several times over, so the size must too. Then start a NEW trade journal and keep the old one, it will be useful for comparison. And above all, set yourself a minimum number of trades before the decision may be revisited.
What to do when no style fits
The most common case: your schedule suits swing while your temperament wants scalping. The usual way out is not a compromise but a separation. Take swing as your main style and run it by the rules, while satisfying the urge for activity on a demo account or in bar replay, where an hour can cover a week of market. The second workable option is to keep intraday trading but at small size and with a hard limit on trades per day. There is exactly one bad option: doing both with real money and without separate journals, because then it is impossible to tell what actually works.
The service has bar replay: the chart advances candle by candle with an honest cut-off of the future, so an evening can cover a month of swing trading. It is the only way to accumulate a sample for a long horizon faster than in a year. Numbers from replay do not replace live trading, but flaws in the approach itself show up immediately.
The chart and bar replayWrite your style down on paper
Answer the three questions from the start of this lesson in writing — hours a day, cost of a round trip on your venue, maximum time without intervening. From those answers pick a horizon using the table and write it in one line: my style is this, a position lives this long, trades per week this many. Below it add a review condition: the number of trades before which you will not change the decision. That note is worth more than any strategy: it will stop you changing style at the very moment when there is least reason to.
Three weeks of swing trading in a row were losing. Time to change style?
Three weeks of swing is about ten trades, and on such a sample the result is indistinguishable from random. The loss says nothing about the approach; it only says little time has passed. Changing makes sense if one of the conditions the style was chosen for has broken: you no longer have time for the checks, fees changed, the instruments lost their travel. A loss by itself is not such a condition — otherwise you will change style precisely when it costs the most.
Why not trade two styles at once?
You can, but only with separate accounting, and almost nobody does it. Without separate journals you get one combined result in which it is impossible to see what works: profitable swing trading can cover lossy scalping for years while you assume both parts are fine. Then there is size: each horizon has its own stop and its own share of risk, and mixing them easily gives double risk on a single move if both positions face the same way. If you really want two styles — two journals, two risk limits and an honest comparison in six months.
