Possibly every newby's question.
ASX - when do you place a trade ?
1. Very first thing when market opens ? (and place order at market)
2. Place order the day before on closing time (closing time price)
3. You wait and see what is happening on open day (first minutes price monitoring prices)
4. you monitoring volume of shares on open day and then decide if it is worth entering ?
This based on charting the trade day before (or even earlier) and market for selection.
