04 — BEFORE YOU ASK
Clear answers.
No surprises.
Can you build any EA for $499?+
Yes. The $499 price covers any clearly defined trading strategy, including complex strategies, for one MT4 or MT5 EA. Complexity does not increase the initial price. We help document your requirements, and you approve the full specification before payment. New requirements or changes to trading conditions after approval are separate paid work.
When do I pay?+
Only after we clarify your requirements, send you the updated specification, and you confirm it is correct. There is no automatic checkout or payment to submit this form.
What do the three days include?+
Development, agreed logic checks and preparation of your initial delivery. The clock starts after scope approval, payment and receipt of all required files. Your brief confirms the exact delivery date. A subsequent revision is scheduled separately.
Do I really receive the source code?+
Yes. You receive the editable source and compiled EA, with ownership of the custom work. We disclose any separately licensed third-party components before agreement.
What counts as a minor revision?+
You get one minor revision for basic presentation or usability adjustments within the approved requirements. It cannot change the agreed strategy logic, entry or exit conditions, or risk rules. Bugs or behaviour that does not match the approved specification are corrected free of charge and do not count as your revision. Changes to approved conditions or new requirements are quoted separately.
Do backtests guarantee profitable results?+
No. We develop your logic; we don’t promise returns. Backtests show historical simulated behaviour under documented settings and depend on data quality, spreads and other assumptions. Live trading can differ and involves risk. Test on a demo account before live use.
How does the October offer work?+
This offer is limited to 100 custom EA projects and ends on 31 October 2026, 11:59 pm IST, or when all slots are booked, whichever comes first. We confirm availability, scope and your payment deadline in the written proposal. Your slot is confirmed after you approve the requirements and complete payment. Sending an enquiry alone does not reserve a slot.
YOU BRING THE STRATEGY. WE BUILD THE EA.
