Stop loss question | Aussie Stock Forums

Have question for my trading platform which changed and they no longer offer a Stop loss option too???
Anyway after a heated discussion about how can you trade properly without stop losses to especially when a crash occurs
my question is.
Can i use my regular platform buy/sell to set a SELL price BELOW the current price? My options are “Best, Market to Limit and Limit

Thanks for any help here as the broker isnt very responsive at this time to my questions as a customer??
