The future of ECNs is questionable. If the exchanges decide to extend trading hours themselves, will there still be a need for ECNs? Only time will tell. Should you engage in after-hours trading?

The commodities market has the CRB benchmark. The stock market also has its own benchmark, or more correctly, benchmarks.

Going back to your early mathematics, the best possible way would be to take the price of all the stocks, add them up, and divide by the number of stocks to arrive at an average.

For one, you would have to account for the many stocks entering and leaving the market. Also would you give the more popular stocks a higher weight than the less known ones? Obviously such a simplistic average would render a lopsided result of the market, where a few trivial stocks could easily
