It was just price matching using computer software (bot). If you know how price matching works in ASX, you would understand why/how.
You can actually break this by putting or pulling the orders at 4.10 pm +/-15sec. I recommend at least 2 quick changes to 'confuse' and hopefully beat the bot. (The bot executes much faster than us but if it is confused at the last sec, u can hopefully beat it). We can also beat the manual buyer/seller too as the bits may just cancel in the last sec.
It is very profitable especially in shares at 0.1/0.2. (100% profit)
YOu can do an experiment: Try put in a sell order at 0.1c say in a 0.1/0.2 stock like EDM after 4pm but before 4.10pm, a buy order of 0.2 will probably appear automatically and the vol will be at least 1 share above your sell, making the indicative price at 0.2. (to draw out any hopeful queue jumping 0.2 sellers) However, if you are not aware, at 4.10pm the buy order will change to 1 share below your sell, making the indicative SP @ 0.1. If you don't cancel your order in time, you may ended up selling yours at 0.1 even though you are hoping to sell at 0.2.
Quite exciting game to play if you do it manually. A bot will probably cancel both buy and sell at the same time just before the 4.10 matching time.
