If you own editable MT4 or MT5 source and can reproduce one defect, I repair it against three written tests. Editable source, compile evidence and handoff checks are included. New bots and cross-platform work remain available after the free brief identifies the right scope.

Agreed cases, editable source and test notes
These projects expose source, compiler-verifiable artefacts and concrete acceptance logic. They are engineering evidence, not trading-performance claims.
A non-trading MetaTrader 5 script that executes eight synthetic entry-state fixtures before timing, duplicate, cooldown and daily-lock rules are connected to broker behavior.
Original MQL5 source and ZIP published in MQL5 CodeBase item #76039
A read-only MetaTrader 5 script that estimates entry-to-stop cash loss in account currency, reserves explicit costs and floors volume to the broker grid without sending an order.
Original MQL5 source and ZIP published in MQL5 CodeBase item #75981
A deterministic Pine Script diagnostic that makes initial-versus-remaining quantity semantics explicit for 50%, 33% and 25% partial exits and emits each tier once on a confirmed bar.

One primary entry, two qualified paths
A repair is the smallest paid result. Complete builds and migrations remain available when the free brief proves that is the actual need.
Primary paid first step
One reproducible defect in buyer-owned or authorized MQL4/MQL5 source up to 500 lines, repaired and retested against three agreed cases.
One simple MetaTrader 5 Expert Advisor built from deterministic entry, exit and basic risk rules, with three written acceptance cases, editable source and reproducible evidence.
Migrate one bounded behaviour from authorized Pine, MT4 or another supported source to a target platform, with platform differences and three parity checks documented.
One primary paid first step
The brief checks whether the 49 USD repair fits before you buy. Complete builds and migrations remain available when your written facts require them, but they do not compete with the smallest useful first result.

Bot Care is a post-delivery option after a successful first order, never a first purchase.
The three written acceptance cases pass, or the agreed delivery is not finished. Report a failing agreed case within 7 days using the original inputs and a reproducible result. I correct that agreed case without an added fee. New rules, another platform, changed broker conditions or a different defect are new scope. No direct checkout occurs on this site. I accept no more than two concurrent funded builds. The next start date is confirmed only after source review and funding; no artificial slots or countdowns are used.
The goal is not merely code that compiles, but behaviour that can be checked against the agreed specification.
I freeze entry, exit, risk, sessions, ownership and edge cases in writing.
I implement the agreed solution with explicit state, guards and useful logging.
I verify compile checks, acceptance examples, parameter sanity and failure modes.
You receive the agreed source, configuration, test notes and setup guide.
Before you hire
The target platform, authorized editable source or complete rules, current and expected behaviour, and three acceptance cases: one expected case, one must-not-happen case and one restart or failure-path case.
Yes. Every applicable repair, build and migration includes editable source, a compiled result when the platform supports it, setup notes and a concise change record.
The three written acceptance cases must pass or the delivery is not finished. One scope-conformance revision is included. This guarantees agreed software behaviour, not trading performance.
A change costs extra only when it adds rules, platforms, strategies, integrations or unrelated defects outside the frozen scope. I identify that before doing the added work.
Data, spread, execution timing, symbol rules, account mode and restart state can differ. The scope freezes those assumptions so the agreed test evidence stays interpretable.
Acceptance is tied to three written cases and explicit exclusions. A revision corrects the agreed behaviour; new features become a separate scope instead of an endless revision loop.

Futures and forex trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing one's financial security or lifestyle. Only risk capital should be used for trading, and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.
Hypothetical performance results have many inherent limitations. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown. There are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. Hypothetical results are generally prepared with the benefit of hindsight, do not involve financial risk, and cannot completely account for the impact of financial risk in actual trading. Market conditions, the ability to withstand losses, and adherence to a trading program can all materially affect actual results.
