Maybe a topic for weekend - Recognising a slow spec market and so backing off trading aggression.
The slump in share trading in the spec end of the market over the last 6 months has notionly been obvious, but it's only a gut feeling.

The number of baggers is very low these days.
The main theory voiced here on HC - spec money moved to top end awaiting the big crash.
Is there a way to monitor graphically total volume/value of all shares on a daily basis of all ASX tickers combined?
Or some other way of separating blue chip from specs in a monetary sense?
Over a period, you read whether market money is going up or down.
I think I read Weinstein referring to a New York stock exchange with this information (something like a Mansfield chart) but I can't readily lay my hands on it.
