Algorithmic trader · Developer

Trading tools that do what you think they do.

I build TradingView indicators and strategies, convert them into MetaTrader 5 Expert Advisors checked trade by trade, and audit trading bots before you pay for a prop-firm challenge. I trade funded accounts myself, under the same daily-loss and drawdown rules you face.

Prop Firm Readiness Audit

Before you pay a challenge fee, find out whether your bot has a real edge and whether it can survive the firm's rules. You get a clear verdict and a written report, even when the answer is "not ready". That answer usually saves more money than any optimization.

No audit can guarantee passing a challenge. The report estimates probabilities from historical data, with every assumption stated. It is a technical review of software, not investment advice.

How the audit works

The same checks I run on my own strategies before they touch a funded account.

Replicate

I rebuild the strategy from your code and confirm it with you on real chart examples before judging any result.

Remove the illusions

Look-ahead bias, repainting, fills at impossible prices, missing costs. Most "great" backtests lose most of their edge here.

Test what it has not seen

Out-of-sample periods and other markets. An edge that only exists in the period it was tuned on is not an edge.

Compare with chance

Random entries with the same exits and risk. If your entries do not beat them clearly, the result came from the market, not the strategy.

Apply the firm's rules

Floating P&L day by day against the daily and total limits, and a Monte Carlo estimate of how often the bot passes or fails.

What you receive

A 4–6 page report with one of three verdicts, the numbers behind it and what to change.

ReadyReady with changesNot ready

Every report has a unique code. Anyone you show it to can verify it here: that it exists, when it was issued, its scope and its verdict.

FAQ

Will the indicator repaint?

No. Signals are calculated on confirmed bars, and higher-timeframe data is requested without look-ahead. I show you how to check it with bar replay.

Will the EA give exactly the same trades as TradingView?

Very close, rarely 100%: data, spread and session hours differ between brokers. That is why every conversion includes a side-by-side trade comparison with each difference explained.

Can you guarantee profits or passing a challenge?

No, and nobody honestly can. I deliver code that does what was agreed, and audits that estimate probabilities with stated assumptions.

Is my strategy kept confidential?

Yes. Your code and rules are used only for your project and are never published or reused.

How do I pay?

Through MQL5 Freelance or another platform with escrow, or directly with 50% upfront and 50% on delivery. Details in the quote.
