What it means
'Trade is disabled' means the platform will not let you open or change positions. Either trading is turned off at the account level, or it is blocked for the specific symbol, or the platform itself is in a read-only state.
Nothing is broken — permission to trade is simply switched off somewhere.
Common causes
You may be logged into an 'investor' (read-only) password rather than the main trading password. The account might be a demo that has expired, or a live account that is not fully activated, restricted, or archived. The specific symbol could be set to 'close only' or disabled. Some accounts are read-only during verification or after a compliance hold.
Step-by-step fix
Check whether you logged in with the investor password — if the title bar or account status hints at read-only, log out and use your main (master) password.
Try a different, clearly open symbol to see if the block is account-wide or symbol-specific. Check the symbol's specification for a 'close only' state. If the account itself is disabled, contact support and ask exactly why — verification, funding, or a hold are the usual reasons.
How to prevent it
Keep your master and investor passwords clearly labelled. Complete account verification promptly. Watch demo expiry dates. Read any emails from the broker about restrictions on your account.
Broker's fault or yours?
Often it is a login or activation issue on your side. But if a broker disables trading on a funded, verified account without a clear, lawful reason — especially when you have open profits or want to close positions — that is serious and you should escalate and document everything.
