MT4 forex grey label: smart buy or legacy trap?
MetaTrader 4 still has a loyal audience and a huge library of tools. Whether a Forex Grey Label on MT4 is a smart buy depends on who you are selling to and how long you expect to stay.

The case for MT4
If your clients already trade MT4 or rely on expert advisors written for it, they may prefer to stay. Familiarity reduces onboarding friction, and some partners and signal services still assume MT4.
The case for MT5
MT5 supports more asset classes and modern account modes, and it is where new development tends to focus. For a brand with no MT4 audience to protect, an MT5 gray label usually ages better.

Cost of changing your mind
Switching later means a migration project, client communication and retesting. Ask the seller what the migration route looks like and what it costs before you sign for MT4.
Total cost of choosing MT4
Count the cost of the platform plus the future cost of moving. Include client communication, retesting of tools and any downtime. If the migration estimate is high, factor it into the decision today or choose MT5 now. Cost surprises are rarely in the first month.
When MT4 is clearly the better buy
It can be the right choice when your target clients overwhelmingly use MT4, when key expert advisors or partners require it, or when you want to match what competitors in your market already offer. In those cases the audience, not the age of the platform, should drive the decision. Record the evidence you used so you can revisit it later.
