A setup can pass a screener and still fail the decision to trade. A useful audit connects each check to the next action: what qualified, what was known, how much exposure was acceptable, and whether an order was actually justified at the available price.
Below is one walked-forward paper exercise. All prices, times, balances and rules are invented teaching assumptions, not market observations, a backtest or a recommended strategy. There is no evidence here that the method has an edge. Passing these checks would establish compliance with the example’s rules, not profitability.
Freeze the question before the candle closes
The instrument is fictional ABC/USD spot on Venue V, without leverage. All times are UTC. Before reviewing the next completed hourly candle, record this rule: its close must exceed the highest high of the preceding 20 completed hourly candles. Exclude the candle being tested from that reference window.
The recorded reference is 50.00 USD. The entry ceiling is 50.50 USD per token; the stop-market trigger is 49.50 USD. Whole tokens only. For this exercise, if the best ask exceeds the ceiling at the final review, skip this decision entirely. Do not leave an order waiting for a later return.
These are fixed constraints for examining the process. Our breakout-screening article explains candidate selection in greater depth; this case follows one candidate beyond that stage.
Verify the candidate and its evidence
At 12:00:02, the saved venue snapshot reports that the 11:00–12:00 candle closed at 50.40 USD. Confirm the instrument, venue, interval, complete reference window and receipt time. The condition passes: 50.40 > 50.00. A still-forming candle or missing reference data would require waiting, not filling the gap from a later chart.
The snapshot supports only the stated price comparison. It does not validate a provider’s performance claim or explain why the price moved. A technical trigger does not read a headline. A news-based rule would need its own verified information and availability time.
For a real method, separately assess rule provenance, historical versus live evidence, costs and limitations using the signal-evidence checklist. This paper exercise continues to show the remaining constraints; it does not turn its invented rule into a validated trading method.
Price the proposed position
Assume a 50 USD planned-loss budget and an allowance of 0.20 USD per token for total entry-and-exit costs beyond the stated prices. At the maximum entry, the planning calculation is:
- Price distance: 50.50 − 49.50 = 1.00 USD per token.
- Planned loss allowance: 1.00 + 0.20 = 1.20 USD per token.
- Whole-token ceiling: round 50 / 1.20 down to 41 tokens.
This is a sizing assumption, not a loss guarantee. A stop can execute beyond its trigger, and actual costs can exceed the allowance. FINRA’s order-types explanation distinguishes stop triggers, market execution and limit prices in securities markets. Check the crypto venue’s actual order rules. Our risk-management guide covers the broader sizing context.
Check the account before adding risk
The fictional account has 10,000 USD in equity: 4,000 USD of existing crypto holdings at current marks and 6,000 USD cash. Counting several holdings does not establish diversification; FINRA’s concentration-risk guidance explains that correlated assets can leave a portfolio concentrated.
Before considering ABC, this exercise set a 500 USD account-level stress budget. In one assumed adverse scenario, existing positions lose 400 USD combined, including their assumed costs. ABC exits 10% below the proposed 50.50 entry, at 45.45 USD, with the same additional 0.20 USD cost allowance. Its scenario loss is 5.05 + 0.20 = 5.25 USD per token.
Adding 41 tokens would give 400 + 41 × 5.25 = 615.25 USD, exceeding that scenario budget. The remaining 100 USD permits only 19 tokens after rounding down: 400 + 19 × 5.25 = 499.75 USD.
At 19 tokens, planned stop-based loss is 19 × 1.20 = 22.80 USD; entry notional is 19 × 50.50 = 959.50 USD, within the cash balance. The stricter portfolio constraint reduces the candidate quantity. The stress result and stop-based estimate are alternative scenarios: do not add them together. Neither is a forecast or a worst possible loss.
Let the final quote stop the trade
At 12:00:04, a fresh quote shows a best ask of 50.80 USD. That exceeds the unchanged 50.50 ceiling. Under the explicit rule recorded earlier, the decision is no trade; no order submitted.
Do not raise the ceiling or claim a fill at the candle close. A buy limit can constrain the price if it executes, but submission does not guarantee execution. Even an acceptable ask would require sufficient available quantity, applicable venue checks and an order plan; a displayed quote is not a completed fill.
This case ends here. No later price path or profit is invented. A subsequent rally would not retrospectively make the rejected entry satisfy the recorded rule.
Save one decision that can be audited
| Gate | Recorded conclusion |
|---|---|
| Screen | 50.40 > 50.00; price condition passes. |
| Information | Completed candle received at 12:00:02; no performance inference. |
| Position | 41 tokens is the stop-based planning ceiling. |
| Account | 19 tokens is the stricter scenario ceiling; 499.75 USD combined loss. |
| Execution | 50.80 > 50.50 at 12:00:04; no order submitted. |
Retain the rule version, source snapshots, arithmetic and rejection reason together. Missing required evidence, excessive exposure or an unacceptable quote can each end a decision. The useful output is a traceable action—including standing aside—not a requirement to find a trade every day.
