MetaTrader was programmed with the expectation that it would shut down at least once a day (as this is how the ‘average’ windows user uses their computer).  Since MetaTrader is running on a VPS, shutting down your MetaTrader probably does not occur to you – but it still has to be done.  The longer MetaTrader is left running, the more space it takes up in memory and the slower it will run.  You do not need to restart your MetaTrader every day, but you should consider restarting it every few days and certainly every week.

If you do not prefer to restart your MetaTrader during the trading week (and risk missing out on a trade), consider restarting during the weekend when the markets are closed.  Remember:  Whatever trading time you lose to restarting MetaTrader, is much less than the time you’ll lose if MetaTrader freezes or crashes.

We recommend 7 or fewer charts running EAs at a time, for optimal performance.  If you wish to run additional charts please consider restarting your MetaTrader slightly more frequently.
