Symbol allowlist and remapping

Two separate controls decide which symbols a repeater copies and what they are called on the follower. The allowlist filters which trades are copied; remapping decides what name the copy is placed under. They are set per repeater.

Symbol allowlist

The symbol allowlist limits a repeater to the symbols you add to it; left empty, as it starts, it repeats every symbol. The allowlist filters the source account's trades, so it lists the source's symbol names — a follower that spells one differently is handled by a remapping, not here.

Symbol remapping

A symbol remapping tells a repeater what a source symbol is called on the follower, because brokers name the same instrument differently. One writes US500 where another writes US 500; gold appears as both XAUUSD and GOLD. Without a remapping the copy is placed under the source's name, and a follower that does not list that name rejects the order.

A remapping has a source symbol, the target symbol on the follower, and optionally its own ratio that multiplies on top of the repeater's multiplier rather than replacing it.

Applies to

A remapping can apply to every follower or to one named follower. This matters when followers are at different brokers: the target list for All followers shows only symbols available on every follower, so it can legitimately be empty. Pointing the remapping at one follower shows that broker's own symbols instead.

Suggestions, never silent rewrites

Trepeat reads each account's symbol list when the account is added and suggests a target when you create a remapping — it recognises decorations such as a trailing m or .raw, the spaces cTrader uses in index names, and a curated list of instruments that go by different names. Where the brokers' own specifications agree on the instrument, that is used too.

⚠️ A suggestion is only ever offered, never applied. Rewriting the symbol on a live order is a trading decision that belongs to the account holder. If Trepeat cannot identify a match it says nothing rather than guessing — silence is the safe failure here, and a wrong instrument is not.

Getting it right before the first copy

Set a remapping for each symbol the follower names differently before you press Run. Symbol naming is the most common reason a copy fails, and it fails at the moment it matters — when a real trade is being copied. Failures of this kind appear as an alert naming the symbol and the follower.

Both platforms read the account's symbol list when you add it, so its remappings can be set immediately. If that read fails, the list fills in when the account first connects — so if the target picker is empty on a newly added account, run its repeater once.
