Confluence doesnt mean some indicators and price action .. confluence conditions can be seen everywhere from structure to entry
The above structure shows you confluence with 2 major concepts in trading world HARMONICS and ELLIOT, shows you the possible areas where you could see confluence of both
The 3rd wave could some times be BAT pattern or DEEP CRAB pattern in impulse, when it comes to elliot correction you will prob'ly see ABCD pattern in formation.
This will give you an idea of how to identify the confluence when you are looking for swing trading
Always keep in mind that there will be internal small patterns within the big pattern do not get confused while doing multi TF analysis thinking which pattern to follow, always follow the higher TF pattern.
