Custom softwarefor crypto trading.

Commission a tool around your own trading rules, or make a specific change to a bot you already run. A project can start and finish with a backtest.

What you can commission

A price alert can be a complete project on its own. If you also need live orders, the estimate will cover when to place them and when to stop.

Backtest a trading rule

Take a rule like “buy when the close exceeds yesterday’s high.” We agree on fees and how fills are simulated, then replay it against historical prices.

What you might receiveThe backtest code, a trade-by-trade profit and loss log, and a summary after fees.

Discuss a backtest

Place orders on an exchange

We build and test software that places orders under agreed conditions. For an estimate, we clarify the market, who decides the rules and order size, who controls the account and API keys, and who starts, monitors and stops live trading. Please discuss any need for trading recommendations or discretionary operation separately before commissioning work.

What you might receiveAn exchange order module, tests for placing, cancelling and stopping orders, and setup instructions.

Discuss order execution

Monitor and recover an existing bot

Record whether a failure happened while fetching prices, sending an order, or checking a fill. Alert the operator and document what to check before restarting.

What you might receiveA runtime log, alert configuration, and a recovery guide for the person on call.

Scoping, estimate and handover

  1. Walk through the manual task

    Tell us what you do today, such as placing a limit order after an alert. If you already use an exchange or data feed, start there.

  2. Decide what to commission

    Review the scope, exclusions, deliverables, price, and timeline. You can commission the backtest now and leave live execution for later.

  3. Check the agreed behaviour

    Test the agreed conditions, such as handling duplicate orders or a lost feed. At handover, review how to start and stop the system.

FAQ

Can I start with just an idea?

Yes. A rule such as “notify me when the price crosses a threshold” is enough to start identifying the data and features you need.

When will I know the cost and timeline?

We prepare an estimate after discussing the exchange, data, order handling, and monitoring requirements. Include a budget or target date if you have one.

Can we discuss an existing bot or a private strategy?

Yes. Start with what the system does today and what you want to change. If you need a confidentiality agreement, raise it before sharing strategy details.
