Common setup issues
EA says MISSING_KEY
You loaded the generic SET or a SET without your licence. Sign into your customer account, download the SET again and load that personalised copy.
WebRequest is blocked
MT5 -> Tools -> Options -> Expert Advisors. Enable WebRequest and add only https://api.tradingsolutions.uk.
EA does not appear in Navigator
Confirm the EX5 is inside MQL5\Experts, then refresh Expert Advisors or restart MT5.
Portal says NOT SEEN
Confirm the personalised SET is loaded, MT5 has internet access, Algo Trading is enabled and the one WebRequest URL is allowed.
Portal says ACCOUNT_MISMATCH
The licence is already bound to another MT5 account. Contact support when you genuinely need to move the licence to another trading account.
No trade opens
This can be normal. Trading Solutions waits until its strategy, market and risk filters allow a setup.
Telegram test fails
Open the official Trading Solutions bot and press START again, then confirm the Chat ID saved on your account matches the number the bot provides.
