Do i need confirmation before i place order for support or resistance aggressive break? if so what type of confirmation I should loo for?
I think that’s very system dependent. As in how your trading or trying to use this phenomenon as an edge. It all depends on how you trade.
There is no such thing as “confirmation”, the market can and will do whatever it wants no matter what you currently see on the chart.
The moment that you believe that price could do something is the moment that you place an order; even if it is smaller than
normal (3 of 5) to begin with.
Be proactive not passive
