Mark Carmona, founder and developer
I’m Mark Carmona, an Automation Engineer and the founder of MarkQuant, based in the Philippines. I develop Expert Advisors for MetaTrader 5, with a focus on automated Gold trading.
My official MQL5 developer profile links back to this website and lists my products and publications. MarkQuant is my software brand; Quintara Gold is its flagship product.
Two approaches to Gold automation
Quintara Gold brings five breakout engines together in one MT5 system. Gold Orchestra combines several strategy families. Their official product listings, demo downloads, licence terms, and updates are available through MQL5 Market.
The developer is Mark Carmona. MarkQuant is the software brand; Quintara Gold and Gold Orchestra are the product names. Product enquiries on this website go directly to Mark at mcarmona1064@gmail.com.
How we present the products
We link to the product documentation and keep strategy descriptions separate from performance evidence. A historical backtest, an early monitoring account, and a trader’s own results answer different questions. None establishes guaranteed future returns.
Our trading guides explain the terminology and provide a practical evaluation process. They are educational material about the software, not personalised investment recommendations.
How to read our testing evidence
MarkQuant writes these guides and develops the products discussed. Product demonstrations and developer tests are first-party evidence. They should be evaluated alongside your own testing and independently inspectable account records.
The Quintara Gold walkthrough labels its historical period, settings and developer build. It distinguishes the chart-footage excerpt from the completed report and keeps the remaining execution warning visible. Its published test summary includes a build fingerprint and a relevant journal excerpt.
A result for one selected month cannot establish performance across other market conditions. A developer build shown in a guide may differ from the current MQL5 Market release. Check the listing and matching documentation before trying to reproduce a test.
If you find an error in a guide, send Mark the page URL and the detail to check. Please remove account credentials and private financial information from any supporting material.
