8GB of RAM should be sufficient if you’re running basic strategies. Since you mentioned having only two charts open, it’s worth considering what’s happening within those charts. Are you running strategy alone, or a strategy with additional indicators? If you’re using indicators along with the strategy, that’ll demand more resources, which means more RAM. In our experience, the 8GB tier works well for simpler setups, like time-based strategies or those with just a few indicators. But as you start working with more complex data, especially high-frequency data like tick data, you’ll notice RAM usage increasing quickly.
