Question 1 - So looks like the odds for TNC to be reach grand final is 8.3 which make sense. but the odds against TNC to reach final is 19.867?(thats just too good to be true)
odds to reach the final is 8.3 correct , but odds against it is 1.053 ( you will find out once you click the red button then the odds will appear in the betting box )
this is called laying , in other words you are taking the opposite bet for someone who wants to get paid 19.867 in case they reach the final
you don't really need to fully understand since as I said you will see the real odds in the betting box once you click the red buttong
Question 2 - I see there is ODDS and OFFERED ODDS, is ODDS the actual odds for the bet?(that would make sense but if that is the case what is OFFERE ODDS for?)
Odds is the real odds you will be getting , same as I explained before
when you lay that specific bet odds is 1.053 ( real odds ) and prefered odds is 19.867 ( you can assume it as the odds for the other guys who is opposing your bet )
Question 3 - I assume liability is the max amount you can bet?
yep when you lay the bet , somehow it doesn't always work for me though so in my experience it's not perfect estimation
it's usually showing when you double click on the selection
Question 4 - What is the different between taker, market/taker, market maker?
My understanding is taker basically just take the available orders. Market/taker would take the available orders and create additional order if it can fulfill the volume you want. Market maker would create order for both side and basically try to profit from the margin.
this section makes you able to put the odds that you want , for example you don't like X8.3 for that team to reach the final and you want X10.00 instead
you simply use that section and create an order , this will let others know that you want X10.00 instead and if someone want to take the opposite of your bet then he will match it
this way you get better odds , but as I stated another player needs to take the other side of the bet so most of the times it will just vanish
