Symbol matching in plain language
Match symbols by exact name, by a familiar wildcard mask, or by regular expression — and see how much of your stream already lines up before you write a single rule.
Regular expressions are a fine tool if you write them for a living. Most people lining up symbols across feeds do not. So the mapping editor now takes three kinds of rule, and you say which one you meant: an exact name, a wildcard mask of the kind you already use everywhere else on the platform (EURUSD*, ?EURUSD), or a regular expression when you genuinely need one. Toolbox never guesses between them — EUR* means what you think it means, and a name containing a dot stays a name.
Suggestions now know what they are suggesting. They used to be built from the feed's own symbol list, which is why they so often proposed mapping a symbol to itself, hundreds of times over. They now look at what your other feeds are actually streaming, group the symbols that differ only by a shared prefix or suffix, and offer you one rule per family — with the count of symbols it lines up and any it would catch by mistake shown up front. Apply it in one click, or ignore it.
Symbols you have not mapped keep flowing. Previously, saving your first rule quietly sent every other symbol from that feed off the screen. Now anything a rule does not match simply travels under its own name, and a symbol is only ever dropped because you asked for it on the rule itself.
Open the editor and it opens with the state of play: how many symbols this feed carries, how many already share a row with your other feeds, and how many are still on their own. Most of the time the honest answer is that you need far fewer rules than you expected.
