Hi MT,
Difficult to quantify the trading style in absolutes, so I'll just briefly outline the components
First to clarify that while the term 'mechanical trading' is generally used interchangeably with 'algo trading', pure algo trading is automated mechanical trading
Any trading based on a structured framework of logic process flow can be categorized as mechanical trading, so long as the desired outcome (scrip selection, scrip ranking, setup alert etc) is generated via a mechanical process (scans, explorations - created/ coded as desired) and not purely by manual analysis of each scrip to identify the desired features
The mechanical component of my trading comprises of suitable trading vehicle selection (scrips as per a combination of various filters). The suitable vehicle selection would differ depending upon the time horizon of the trade (different filters). Here, am primarily outlining the process flow for intraday. The next step would be segregation of scrips in the categories of up, down & sideways (trend state as per higher timeframe of use). The next step would be to narrow the focus onto scrips which are aligned with the trend state of broad market (as per timeframe of use). These steps are a part of advance preparation for the next session.
At the start of the session, scan of focus scrips is started (and is repetitive at chosen intervals). The scan issues an alert when a defined 'setup(s)' is formed/ detected and ranks the setup(s) in addition (as per defined criteria). Remember, I said setup and not trigger!
Till this point the process is mechanical. The mechanics are designed and utilized as a labour saving efficient tool to aid the cognitive process. From here on the discretionary process takes over to decide upon the target scrips (based upon ranking as well as situational awareness). The position size is mechanically calculated simultaneously upon trigger formation. Discretion is used to modify it either as conservative or aggressive. Trade is entered manually. Trade management is discretionary + mechanically aided as a backup
