Build a 90-Day Trading Record: Scope, Costs and Missing Data

A 90-day trading record is a report for a defined observation window. It can show what the available records contain over that interval, but ninety days alone does not establish statistical significance, consistent future returns or independent verification. Define the account, dates, source and calculation rules before reviewing the outcome.

Fix the reporting window before seeing the result

Write down the inclusive start timestamp, exclusive end timestamp and timezone so the interval covers the intended ninety calendar days. Ninety days is not necessarily the same as three calendar months. State whether a trade is assigned by entry time or exit time, and how positions spanning a boundary are treated.

Record the account identifier, currency, broker, account context and strategy version. Keep any earlier available history rather than implying that the selected window is the account's entire life. If you show several accounts, disclose all included and excluded accounts and why they were selected.

Create the observation log

Preserve original exports and separate redacted sharing copies. The MT4 history documentation explains selectable reporting periods; the MT5 statement documentation describes the exported account report. Check the actual file, not just its filename.

Separate trading profit, costs and cash flows

Reconcile the opening balance plus net external flows plus net realised trading result to the closing balance. State whether commissions, swaps and other charges are already included in each profit field. Avoid subtracting a fee twice or counting a deposit as a gain.

Illustrative calculation, not an observed account: a USD account starts with $10,000, has no deposits or withdrawals, and records net realised results of +$200, −$150 and +$250 in three consecutive, non-overlapping thirty-day blocks. All stated trading costs are already included. If there are no open positions at either boundary, the total is +$300, the closing balance is $10,300 and the period return is 3%. This is a description of that invented sample, not a monthly target or an annual forecast.

Report the losing block as well as the gains. With external cash flows, a return calculation needs a disclosed method and flow timing; the simple no-flow example cannot be reused unchanged. Do not annualise a short profitable period as a prediction.

Check whether your curve measures balance or equity

A closed-trade balance series records realised changes. An equity observation can include open-position profit and loss at its timestamp. Neither a daily snapshot nor a closed-trade reconstruction necessarily captures the worst floating loss between observations.

MyVeridex currently offers MT4 and MT5 investor-password connections and supported statement imports. The importer reconstructs daily history from closed transactions; it cannot restore a complete historical floating-equity path. Label that history as reconstructed. It cannot establish that every intraday prop-firm loss rule was respected.

Check the source's actual first and last records and the last successful sync, rather than assuming that connecting now creates ninety days of complete history. Use the evidence and reconciliation checklist to document gaps. MyVeridex product status checks are explained separately in the account-check reference; they are not an independent audit.

Ninety days is a window, not a sample-size rule

The number and dependence of trades, changes in exposure, strategy selection and conditions encountered all affect what a sample can support. A large order count can contain repeated exposure to the same market event. A quiet ninety-day interval may not include the conditions that matter to the strategy.

Report trade count, activity distribution, open exposure, costs and any changes made during the period. If you make a statistical claim, it needs a defined hypothesis, appropriate analysis and disclosed assumptions. Do not infer significance from a universal trade minimum, a calendar duration or a MyVeridex status threshold.

Deliver the observation report with its limits

State the exact window, account context, data routes, selected accounts, included costs, reconciliation result and missing observations. Summarise what happened without claiming that a recipient must accept it or that the period improves your chance of passing an evaluation. Ask the recipient for its actual requirements.

For a planned prospective test, define decisions before collecting new observations; the forward-test protocol describes that separate task. A retrospective ninety-day report and a prospective test are not interchangeable. Both need honest disclosure and neither guarantees future performance.
