Who I build for
Built around the market you actually trade.
Forex and gold are the core of the work, alongside prop-firm accounts. Stock, index and CFD strategies on MetaTrader 5 are available too. Each market has its own spreads, sessions, gaps and rules, so every Expert Advisor is specified around them, not copied from a template.

About Variontrade
You talk to the developer, not an account manager.
I’m Praveen Divvala, founder of Variontrade and an MQL4/MQL5 algorithmic trading developer with 3+ years of experience building custom Expert Advisors and indicators for traders around the world.
Every project starts with me sitting down with you to understand the strategy, then turning it into a clear technical specification before I write any code. What you receive is tested, documented and easy to adjust.
Spec before code
Your idea becomes a written specification you approve first.
Adjustable by design
Modular code with input parameters, so you fine-tune without editing code.
Tested before delivery
Strategy Tester runs across pairs and timeframes, plus demo forward-testing where it matters.
Support afterwards
Bug fixes and refinements from live performance feedback.

How it works
How I turn a trading idea into a working EA.
The same four-step workflow on every client project, so nothing is left to guesswork.

Requirement gathering
We go through your trading idea in detail: entry and exit conditions, indicators, risk tolerance, preferred currency pairs and timeframes, and special conditions such as news avoidance or session restrictions. Your manual strategy becomes a clear technical specification before any code is written.
- 02
Coding & development
The Expert Advisor or indicator is written in MQL4 or MQL5 for your platform. Core trading logic comes first, then risk management: stop-loss, take-profit, trailing stop-loss, breakeven and position sizing. The code stays modular, with adjustable input parameters so you can fine-tune settings without touching code.
- 03
Back-testing
The EA runs through the MT4/MT5 Strategy Tester on historical data across multiple pairs and timeframes. Consistency, drawdown and behaviour in trending versus ranging and high versus low volatility markets are checked, and logic is refined until performance is stable. Where it matters, a forward test on a demo account validates real-time behaviour before going live.
- 04
Delivery
You receive the final compiled .ex4/.ex5 file (or source code, if agreed) with a short setup guide covering installation and key input parameters. Support, bug fixes and refinements based on live performance feedback stay available afterwards.

FAQ
Expert Advisor development, answered.
Short answers to what traders ask before commissioning an MT4 or MT5 EA.
What is an MQL4/MQL5 Expert Advisor developer?
An MQL4/MQL5 Expert Advisor developer writes trading robots (Expert Advisors, or EAs) and custom indicators for the MetaTrader 4 and MetaTrader 5 platforms. An EA automates a trader’s entry, exit and risk rules so the strategy runs without manual execution.
How much does a custom Expert Advisor cost?
It depends on how complex the rules are: the number of entry and exit conditions, filters, markets, and how much testing is needed. Send your strategy and you will get a scoped quote before any code is written.
How long does it take to build an EA?
Simple single-entry strategies are quicker than multi-condition, multi-pair systems. The timeline is confirmed in your quote once the specification is agreed.
How do I turn my trading strategy into an Expert Advisor?
Share your strategy rules: entry and exit conditions, indicators, risk tolerance, pairs, timeframes and any session or news restrictions. Those are converted into a technical specification, coded in MQL4 or MQL5, back-tested in the Strategy Tester, then delivered as a compiled .ex4 or .ex5 file with a setup guide.
Can you build an EA for prop firm challenges like FTMO?
Yes. Prop-firm EAs are built around the rules your firm publishes: daily loss and maximum drawdown guards, a news filter, risk-based lot sizing and session or weekend rules. No EA can guarantee passing a challenge, but a rules-aware EA stops the account being broken by careless risk.
Can you convert my TradingView Pine Script strategy to MT4 or MT5?
Yes. Pine Script indicators and strategies are rewritten in MQL4 or MQL5 as MetaTrader indicators or Expert Advisors, then checked against the original chart signals before delivery.
Do you build gold (XAUUSD) Expert Advisors?
Yes. Gold EAs include news avoidance, spread and slippage safeguards and risk-based sizing, because gold is fast and spreads widen around news.
Can you automate stock, index or CFD trading?
Yes, where your broker offers those instruments on MetaTrader 5, with market-hours, gap and contract-size handling. Strategies on other platforms or broker APIs can be discussed; you will get an honest answer on what can be built.
Can you fix, upgrade or convert an EA I already have?
Yes, given the source code. Common jobs are MT4 to MT5 conversion, bug fixes, and adding trailing stop, breakeven, a news filter or drawdown protection.
Do you build for MT4, MT5, or both?
Both. Expert Advisors and indicators are written in MQL4 for MetaTrader 4 or MQL5 for MetaTrader 5, depending on your platform.
How is an EA back-tested before delivery?
The EA runs through the MT4/MT5 Strategy Tester on historical data across multiple pairs and timeframes. Drawdown, consistency and behaviour in trending versus ranging and high versus low volatility markets are reviewed, and the logic is refined until results are stable. Where it matters, a forward test on a demo account follows.
What risk management features can an EA include?
Stop-loss, take-profit, trailing stop-loss, breakeven stop-loss and position sizing, plus news avoidance, session filters, and drawdown or equity safeguards, all exposed as adjustable input parameters.
Can an EA avoid trading during news events?
Yes. The News Factor EA reads the Forex Factory economic calendar, pauses trading before high- and medium-impact news, and resumes safely afterwards to avoid volatility spikes and slippage.
What do I receive when the project is finished?
The compiled .ex4 or .ex5 file (or the source code, if agreed), a short setup guide covering installation and key input parameters, and continued support for bug fixes and refinements.
Can you code a Zone Recovery, martingale or breakout EA?
Yes. Delivered strategy types include Zone Recovery, High-Low Breakout, Support & Resistance, Martingale/Averaging, Zig Zag and custom indicator-based EAs.
Do you work with clients outside India?
Yes. Custom EAs and indicators have been delivered to 90+ retail and institutional clients, with active clients in Europe and India.
Does an Expert Advisor guarantee profits?
No. An EA executes a strategy exactly as defined; it does not make the strategy profitable. Back-testing shows how a strategy behaved historically, and past performance does not guarantee future results. Trading leveraged products carries a high risk of loss.
Who can build an MT5 Expert Advisor for me?
Variontrade builds custom MT5 Expert Advisors in MQL5, and MT4 EAs in MQL4. Send your strategy rules through the contact form or WhatsApp and you get a written specification and quote before any code is written.
Can you convert an MT4 indicator to MT5, or turn an indicator into an EA?
Yes. MT4 indicators can be rewritten in MQL5 for MetaTrader 5, and an indicator you trade by hand can be turned into an Expert Advisor that takes its signals automatically, with stop-loss, trailing and position sizing added.
Do you build MetaTrader scripts and trade management tools?
Yes. Scripts handle one-off jobs such as closing all trades or placing order grids, and trade manager EAs apply stop-loss, trailing, breakeven, daily loss limits and equity protection to every position, including manual trades.
Can you build a trade copier or a Telegram signal copier for MT4/MT5?
Yes, on request. A copier can mirror trades between MT4 and MT5 accounts with lot scaling and symbol mapping, or read signals from a Telegram channel and place them as orders. It is built around your accounts, brokers and signal format.
