Experimenting with trading software and a few indicators may help. I'm reading Alexander Elder's 'New Trading for a Living' at the mo, available on-line with a bit of creative searching. His New High-New Low index might fit the bill will a price and/or MC filter to suit the spec end of town. ....The New High–New Low Index (NH-NL) tracks the behavior of market leaders by subtracting the number of New Lows from the New Highs. In my experience, NH-NL is the best leading indicator of the stock market.
Or something along the lines of the Stockbee Market Monitor (again filtered for the spec market) might do it....he also runs a Market Monitor page for the US market, see MM in the main menu. https://stockbee.blogspot.com/2014/08/how-i-get-market-monitor-numbers.html
Excellent site for TA that one, no end of learning available there.
