When I deploy a live algorthm and I get the following error message due to using 25 symbols and second resolution:

"We currently only support 15 second at a time due to physical memory limitations"


Even after this message the algorithm deploys and continues to trade. My question is what exactly is happening when this memory limitation is shown? Is my algo being limited somehow? Am I only receiving 15 symbols worth of data? It seems like it trades and continues normally so I am a little confused.
