This is not a trade. I thought it might be helpful to post the intraday chart (5-min) of ASX200 index. If one pays enough attention to the chart, it is not too difficult to draw out the structure in terms of supply, demand zones.

First of all, I assume you have the knowledge to identify supply, demand zones. Support , resistance level is just the cluster of supply demand zones. The basis of this analysis is , price tends to rebound at the demand zone (reverse is true for short side), and the broken level tends to serve the opposite.

Have a look at the 5-minute chart below.
