Wrong Amount error means that the Trade Copier tries to close a trade with a bad amount, or it tries to open a trade with an amount not allowed by the broker. It could also mean that there are different symbol names (i.e, with a suffix) on the slave broker, and the given symbol is not properly configured at the broker side, meaning another symbol needs to be used. In that case, you have to create a mapping with the symbol that is tradable.
