Test a Trading Algorithm: The Deployment Readiness Checklist

Deployment readiness is an operational question, separate from a profitable historical result. The aim is to check what the exact software will attempt, which failures remain possible, who can stop it and whether that use is permitted. No test guarantees safe execution, profitability or a passed evaluation.

1. Identify the proposed deployment

Record the executable/version, preset, platform, dependencies, symbols, account model, server clock and intended operator. Match required inputs and units to the developer's documentation. An MT4 binary is not an MT5 binary; a product name does not establish support for every terminal or account mode.

Before connecting anything, check the precise provider, programme, phase, size, strategy, access, copying and add-on conditions. An evaluation can itself have a purchase fee or simulated trading. Demo status is not permission to use any software, and a test is not a request to buy a challenge or place a trade.

2. Reproduce known behaviour before a broad test

Write expected inputs, decisions, order sizes and attempted exits for controlled cases. Compare logs and visual tester output with those expectations. Include no-signal cases, missing values and conflicting positions, not only examples that would make a profit.

Keep historical test evidence separate: exact data, costs, modelling mode, selection process and held-out evaluation. MT5 can simulate execution delays; a recorded or generated-tick mode still does not reproduce every broker fill. A 99.9% label is not operational certification. Use the separate backtesting workflow for the reproducible historical package. Vary documented historical cost and delay assumptions and inspect sensitivity without treating a resampled scenario as the worst possible future drawdown.

3. Check account-level calculations and attempted controls

Verify actual contract size, tick size/value, account currency, volume minimum/step/maximum, stop/freeze restrictions and margin. Fixed lots and percentage sizing are alternative implementations that both need checking. Account leverage is a margin setting, not the monetary loss per tick for an unchanged position.

Replay the actual daily/total loss formula, timezone/reset, open and closed P&L, costs, pending orders, other systems and manual positions. Check what the software attempts before a threshold, and whether it prevents new exposure, changes orders or closes positions. These actions can fail or fill beyond the planned price; do not describe a guard as an uncrossable cap.

4. Test failures in an authorised environment

Check initialization and settings reload, rejected or partial orders, insufficient margin, market closure, lost connection, restart and incomplete data. Confirm that a reconnect does not duplicate an order or forget existing exposure. Log the event, intended response and observed outcome; do not create outages or test orders on someone else's live account.

For a self-operated EA, verify the required running terminal, permissions and any trusted dependencies. Do not enable unknown DLL or network access just to make a test run. A VPS is one hosting option, not an uptime guarantee. The separately hosted JPTC Algo requires no customer installation or VPS; that does not turn EA Hub downloads into a hosted service.

5. Observe an authorised demo without equating it to deployment

A later demo run can reveal current scheduling, connection and order-handling issues. Record requested and executed timestamps/prices, rejects, spread, costs, exposure and account calculations. Compare the event sequence with the specification and investigate differences. Demo liquidity, fills and charges may differ from another account.

Choose observations for the strategy's frequency, coverage and unresolved questions. No fixed three-to-six-month period or number of trades proves readiness or statistical significance. Monitoring should capture incidents and configuration changes as well as results; a company statement page does not connect to or audit every user's account.

6. Make a documented decision and keep the limits visible

Before any later deployment decision, list the exact permitted use, evidence version, unresolved failures, loss-control limitations, monitoring owner, suspension criteria and recovery procedure. A missing answer is a condition to resolve, not a reason to increase size. Retain the previous version and retest changes outside the observations used to choose them.

JPTC EA Hub documentation and file-specific reports should be checked for the selected download. The Algo results page publishes its own monthly broker figures, not an independent audit or proof for another EA. This checklist establishes no mandatory move to real capital, scaling schedule, pass probability, guaranteed compliance or Reward.
