# RW Manager MT4

RW Manager uses MetaQuotes Library to perform connections to the MetaTrader 4 server. This library implements some caching techniques for groups and symbol representation on the local drive where RW Manager started (in the folder ‘bases’). As a result, it is highly recommended to restart RW Manager when:

* configuration for a Symbol was changed, for example (Margin Call, Stop Out, Commission Settings and others)
* configuration for a Group was changed, for example (Execution Type, Margin Currency, Margin Settings, Trading Sessions, and others)
* configuration for a Group Symbol was changed, for example (Spread Markup, Commission Settings)

Also, it is a good practice to restart RW Manager during the rollover period to request the latest MetaTrader 5 configurations.
