# Trading bot code review, audit and repair URL: https://fincodelabs.com/en/services/trading-bot-code-review · Publisher: Fincode (Fincode Yazılım ve Teknoloji A.Ş.), Istanbul, Turkey · Updated: 2026-11-06 Bought or inherited a trading bot and unsure how it handles failures? Fincode reads the code and delivers a written report, ranked by priority. If you want the problems fixed, repairs are quoted separately. The audit covers the software, never whether your rules will make money, and it is not a security certificate: the report states findings. ## What is checked ### API key handling Where keys and secrets live, whether they appear in code, repositories or logs, which permissions the software needs, and whether withdrawal rights are off and IP restriction is used where the platform supports it. ### Error handling What happens on exchange errors, timeouts, dropped connections and restarts. Whether a failure stops safely or carries on silently, and whether an unknown order status is treated as a failed order. ### Rate limits Whether request and order limits are tracked, whether rate-limit responses are honored, and whether retries and reconnections wait before trying again. ### Order state Whether partial fills are tracked, duplicate orders are prevented, and the software's view of open orders and balances is checked against the exchange, including after a restart. ### Risk limits and emergency stop Whether limits such as maximum position size and a daily loss limit run independently of the trading rules, and whether there is an emergency stop that works when the rest of the code does not. ### Logging and alerts Whether every decision, order and fill can be traced with a timestamp, whether secrets stay out of the logs, and whether anyone is told when something goes wrong. ## What you receive A written report. Bugs, security risks and performance risks are listed in order of priority, so you can see what to fix first. If you want Fincode to make the repairs, they are quoted separately and follow the same [written scope and test stages](https://fincodelabs.com/en/how-we-work) as any other project. The [sample code review report](https://fincodelabs.com/en/samples/code-review-report) shows the format, with every finding reproduced on a small, deliberately flawed demo bot you can download and run. ### What we need from you The source code, and the right to share it with us. Tell us which platform it runs on and how it is deployed. Logs help, with any secrets removed. **Do not send API keys.** Remove keys and secrets from anything you share. A code review does not need access to your exchange account. ### What the review does not cover - Whether your rules will make money - Advice on strategies or parameters - Running the bot or watching positions - A security certificate: the report states findings ## Questions about code review ### Can you fix the problems you find? Yes, on request. The report comes first, and repairs are quoted separately. You can also take the report to another developer. ### The bot came from a marketplace or another developer. Can you still review it? Yes, if you have the source code and the right to share it. Without source code there is little to review. ### My bot was written with ChatGPT or another AI tool. Can you review it? Yes, if you have the source code and the right to share it. You get the same written report, with findings ranked by priority. ### Will you tell me whether my strategy is any good? No. The review covers the software. Fincode does not recommend strategies, and strategy and investment decisions are yours. ### Do you need my API keys or exchange login? No. A code review works from the code. Remove keys and secrets before you share anything. ### How is the price set? You get a written proposal before any work starts. Fees depend on scope and effort, not on trading volume or results. ### We have a fintech product, not a bot. Is this the right service?
