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.

What you get

Everything a working trading robot needs.

Fully automated trading

  • Entry and exit rules coded exactly to your spec
  • News, session and drawdown/equity filters
  • Delivered as a compiled .ex4 or .ex5 file
  • MetaTrader 4 (MQL4) or MetaTrader 5 (MQL5)

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.

PropFirmEA.mq5
// adjustable inputs, no code edits needed
input double RiskPercent   = 1.0;
input double MaxDailyLoss  = 4.0;
input bool   UseTrailingSL = true;
input int    NewsPauseMins = 30;

void OnTick()
{
   if(DailyLossHit(MaxDailyLoss)) return; // protect account
   if(HighImpactNewsNear(NewsPauseMins)) return;
   if(EntrySignal())
      OpenTrade(LotsByRisk(RiskPercent));
}
  1. 01

    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.

  2. 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.

  3. 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.

  4. 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.

Chat on WhatsApp (opens in a new tab)

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.
