data retention

Data Retention, Symbol Monitoring Options

This is one of the least understood yet most important aspects of Investor/RT. Each symbol that you add to Investor/RT has monitoring properties and data retention properties that control how Investor/RT collects and retains historical data on the symbol. You may choose to collect every tick (trade) that comes in on your symbol and maintain them all for later analysis, or you may just choose to view the prices as the ticks come in, and then discard the data.
