Identifying Overtrading

What are the parameters to identify Overtrading by Active Traders?
Some of the following can be of help.

1. Number of Trades
2. Total Trading Volume
3. Vig to Trading Capital Ratio
4. Number of Instruments Traded
5. Duration in the Trade ( minutes held)
6. Number of Orders Placed / Cancelled Orders
7. Number of Unplanned / Impulsive Trades ( which are based on " Breaking News", Based on Other Traders's Positions, Reacting to Opinions of Other Traders )
8. Position Size in a single Trade ( Above Avg Size)
9. Number of positions at a particular point of time ( More than two ?)
10. Tight stoplosses ignoring the Logical stops ?

As I struggle to cut down overtrading , I understand the Broker's ( Market Infrastructure's) way of turning thr trader's networth into his own through VIG, SPREAD, SLIPPAGE.
