Choosing a holding clock
An evaluation runs over days to weeks. Match your model to that window, not to your adrenaline.
One of the quietest mistakes a candidate makes is choosing a trading speed by temperament rather than by the evaluation timetable. Scalping feels productive, but it multiplies the number of decisions — and every decision is a chance to over-size, chase or break a rule. A slower clock makes fewer, better-considered calls, which is usually a better fit for a deadline measured in weeks.
The four clocks, and which suits an evaluation
The desk we point to runs four mean-reversion models on different clocks. They are not four strategies; they are one logic applied at four speeds, each graded against its own return spread:
| Model | 2026 YTD P&L | Win rate | Signals |
|---|---|---|---|
| Day Trade same-session, intraday window | +95% | 67.5% | 308 |
| Multi Hour part of a session to a couple of sessions | +404% | 71.4% | 262 |
| Swing Trade roughly one to four weeks | +225% | 74.4% | 78 |
| Investing long-horizon, highest-conviction | +502% | 73.8% | 42 |
For most evaluations, the Multi Hour and Swing Trade clocks fit best: enough calls to reach the target inside the timetable, but slow enough that each one can be sized and considered properly. The Day Trade clock can work for a candidate who genuinely has the screen time and the discipline for it, but it asks more of both. The Investing clock is usually too slow for a fixed-deadline evaluation. You do not have to buy the whole book — the single-model plan at $20 a month exists precisely so you can follow the one clock that matches your program; the all-models plan is $50 a month on a 14-day free trial, and a $5,000-a-quarter Pro Access tier exists for heavier users. There is no money-back guarantee, so the trial is the test — use it to confirm a clock fits before you commit a fee.
The rule of thumb
Pick the slowest clock that can still reach the target inside the time limit. Slower means fewer decisions, fewer chances to break a rule, and more room to respect the drawdown — which is the whole game. Speed is a feature, not a virtue; the clock that passes is the one that fits the timetable while leaving you calm enough to follow your sizing plan.
