I build MetaTrader Expert Advisors, custom indicators and TradingView strategies in MQL4, MQL5 and Pine Script, with full source code, honest testing, and no win-rate promises.
Unedited MetaTrader 5 report: FTMO demo feed, $100,000 2-Step Phase 1 account, every tick based on real ticks, 100% history quality, January to August 2026. A historical test, not a prediction. Read the case study
Platforms I build for
Every Market product ships for MT4 and MT5; Pine Script tools run on TradingView (referral link).
VPS hosting
Low-latency hosting for a MetaTrader terminal. Referral link.
Some of these are referral links. How that works.
Your written rules, an existing EA, or annotated charts become an MT4 or MT5 robot with hard stops, session and spread filters and risk-based sizing. Includes one-click trade manager panels and turning an indicator you already trust into an automated EA.
Daily-loss and total-loss floors that halt inside the firm's line, day anchoring the way the firm measures it, minimum-day counters, best-day gates, and state that survives a restart. Sold as engineering, never as a promised pass.
Pinned spreads, rolling windows across regimes, custom fitness metrics, and a results table that keeps the losing runs in. A backtest is a test, not a sales aid.
Signals evaluated on closed bars only, alerts that fire once, and scanners that watch every symbol and timeframe in your list from one chart without draining the terminal.
Pine v6 indicators and strategies delivered as the .pine source, not an invite-only script. Conversions are rewrites checked signal by signal against the original, with the differences that cannot be reproduced stated up front.
The rules between the message and the order: max lot caps, symbol mapping, duplicate protection, and a queue-and-poll bridge for TradingView alerts, because MetaTrader cannot receive a webhook directly.
Root-cause fixes with a before-and-after report, upgrades to existing code, ports between MT4 and MT5 in either direction, and the validation pass an EA or indicator needs to be accepted on the MQL5 Market.
Every figure below is transcribed from a Strategy Tester report or a public MQL5 page. The weak rows stay in.
XAUUSD H1, $6,000 start, 40-point pinned spread, MetaTrader 4 Strategy Tester, 12 months.
Historical backtest. Not a prediction of future results.
XAUUSD M1, $10,000 start, 25-point pinned spread, real tick-built data, 11 rolling 14-day windows plus one 6-month run per profile.
Historical backtest. Not a prediction of future results.
708 lines of Pine v5 in, 1,472 lines of MQL4 and 1,627 lines of MQL5 out, one 40-input block on both platforms.
Port verified bar by bar against the TradingView original.
20 symbols x 9 timeframes, entry, stop and target per row, new-bar gating so a quiet tick costs 180 timestamp reads.
Sold on the MQL5 Market for MT4 and MT5; passed MetaQuotes validation on both.
Every port is a rewrite checked signal by signal; the features that cannot be reproduced on MetaTrader are documented, not hidden.

Session boxes, auto Fibonacci, fair value gaps, breaker blocks, liquidity targets, confluence zones and a journal exporter. Free, with source.

Before any code exists I write your rules back as a specification, covering what they do not yet answer: conflicting signals, session close, gaps, widening spread, rejected orders. That step is what prevents rework.
Zero errors, zero warnings. Broker constraints (stop levels, lot steps, symbol names, margin) are read at runtime rather than assumed. Signals are evaluated on closed bars only.
Strategy Tester runs with the conditions written down: model, pinned spread, deposit, period. Rolling windows across regimes where it matters, the battery repeated at a wider spread, and the weak results shown.
Full source code, the compiled files, a setup guide, a video of the system running, and support afterwards. Nothing is locked to my machine.
Fixed-price listings on Upwork start at $60 for a fix and $95 for an Expert Advisor, with escrow and milestones handled by the platform. Or send your rules to info@kestutisbalciunas.com and I write the spec back first.
92 listings, 46 products, each for MT4 and MT5: 6 Expert Advisors, 23 paid indicators and 17 free ones. Every purchase, licence, activation and demo is handled by MetaQuotes' own Market system.
The six Expert Advisors are grid and recovery engines, and their listings say so plainly. They are not prop-firm challenge tools. The indicators are dashboards, scanners and non-repainting entry systems, most of them ported from TradingView originals.
MQL5 seller page, 2026-08
Installation guides for every product, technical posts on the MQL5 blog, and 7 free tools in the MQL5 Code Base with their source: session boxes, automatic Fibonacci levels, fair value gaps, breaker blocks, liquidity targets, confluence zones and a trade-journal exporter.
I am Kestutis Balciunas, an algorithmic trading developer. Trading forex, indices, commodities and derivatives since 2010, and writing the software behind it since 2016. That combination is what catches the problems most developers miss: broker execution differences, spread and slippage, stop-level limits, multi-timeframe conflicts, and backtests that do not survive contact with live trading.
I publish and support 92 listings on the MQL5 Market, so my code is held to a standard beyond compiling on my machine.
No, and nobody honestly can. I build the logic you specify, test it under stated conditions, and show you the report including the parts that are not flattering. What the software does after that depends on the market and on how you run it.
Yes, on every job. You receive the .mq4, .mq5 or .pine source together with the compiled files, a setup guide and the test report. Nothing is locked to my machine or to a licence server.
Any MetaTrader 4 or 5 broker. Symbol names with prefixes or suffixes, stop-level limits, lot steps and margin rules are read from the broker at runtime rather than assumed. If a broker constraint changes the design, I say so in the spec.
I can make it obey the firm's rulebook in real time, which is what most challenge accounts actually fail on. Daily and total loss floors that halt inside the line, correct day anchoring, minimum-day and best-day rules, restart-safe state. Whether the market delivers the target inside the window is not something any developer can promise.
No. Signals are evaluated on closed bars only, so a mark that has printed does not move or disappear later, and alerts fire once per bar. Where a TradingView original relies on intrabar or lookahead data that MetaTrader cannot reproduce, I tell you before the job starts.
No. It breaches MetaQuotes terms and the original author's rights. If you have lost your source, I can rebuild the logic from your written rules and your test reports.
In the Strategy Tester with the conditions written down: model, pinned spread, deposit, period. Where it matters I run rolling windows across trending and choppy regimes, repeat the battery at a wider spread, and force the safety limits to fire so the report shows they work. You get the report files, not a screenshot of the best run.
Yes. Upwork is the simplest route for fixed-price jobs because it handles escrow and milestones. For direct work, email info@kestutisbalciunas.com with your rules and I will write the spec back before anything is paid.
The form on the contact page takes your rules and your files, and the specification comes back before anything is paid. Upwork is best for a fixed-price job with escrow. Telegram is fine for a quick question.
