Biyas....ur caps are hurting me
Both strategies are good, it depends wether u like to trade with the trend, or like to fade it.
I personally feel that buying above resistance is better, at least you can exit in quiet times, if trade is not working out.
But if u are short, and price blows thru resistance, squaring up in a fast rising market may be a bit on the difficult side, as big orders cannot be executed at a good price.
I have done both types, and feel that buying above resistance better.
I got stuck quite a few times when my sl was triggered but not executed.
anything above 10,000 qty becomes difficult to trade when prices are moving fast.
Hope this helped you.
