Trailing Stop Calculator

How the disclosed stepped trailing rule is calculated

The model begins with one entered favorable reference, not a stream of ticks. For a buy it must be at or above entry; for a sell it must be at or below entry. The page calls it a reference rather than current price because the user may be inspecting a recorded high, low or other documented favorable level.

Activation distance controls when the trailing rule becomes active. Before the favorable movement reaches that many pips, the entered initial stop remains unchanged. At activation, the first stepped reference equals the activation threshold even if the favorable price has already moved farther.

The reference advances only in complete entered step increments. Any remainder is ignored until another full step is completed. This makes the arithmetic stable and auditable: the same entry, favorable reference, activation and step always produce the same completed-step count.

Trail distance is then measured from the stepped reference, not directly from every fractional favorable price. For a buy the candidate stop sits below the stepped reference; for a sell it sits above. The initial stop remains a one-way floor for a buy or ceiling for a sell, so the calculated stop never loosens past the entered starting level.

A positive applied-stop movement from entry means the stop level sits on the gross-profit side of entry. It does not mean a profit is guaranteed because spread, gaps, trigger basis, slippage, rejection and costs can change the realized close.

MetaTrader 5 describes its built-in trailing stop as platform-side logic that checks new quotes and moves a stop when profit increases. It also notes that the terminal must be running for the trailing process itself. This page is not connected to that process and does not claim identical timing or update rules.

Worked example from the audited fixture

How to interpret the result

1. Check the activation status first. When the rule has not activated, every derived trailing reference remains withheld and the initial stop stays applied.
2. Read completed steps as a count under this one rule, not as a record of platform modifications. No tick sequence, journal, latency or ten-second MetaTrader processing interval is observed.
3. Compare the stepped reference with the entered favorable price. The difference is the uncompleted remainder plus any trail distance effect, so the applied stop can be farther from the entered reference than the trail setting alone.
4. A positive stop-from-entry output describes gross price geometry. It excludes spread, commission, financing, slippage and the difference between trigger and fill prices.
5. Do not tighten activation, trail or step parameters solely to produce a higher locked-pip number. The page contains no evidence about stop-out frequency, future volatility, strategy expectancy or whether a different setting would improve results.
6. Before using a live platform, confirm whether its trailing parameter is points or pips, whether the logic runs on the terminal or server, how often it modifies, which price side triggers and what minimum stop or freeze levels apply.

Assumptions and limitations

• No live quote, tick sequence, chart, account, position, order, terminal, Expert Advisor, copier or broker server is connected.
• The favorable reference is one user-entered value. The chronological path that produced it is unknown and no intrabar ordering is reconstructed.
• The explicit stepped rule may differ from MetaTrader built-in trailing, broker mobile apps, web terminals, scripts, Expert Advisors and signal-copy logic.
• Pip size comes from stored site metadata and may differ from the broker’s point, tick, digits and informal pip convention.
• Stop trigger basis, spread, execution, gaps, slippage, modification rejection, freeze levels, costs and terminal downtime are excluded.
• No activation distance, trail distance, step, stop, position management method, platform, strategy, signal or trade is recommended.
