One minute chart observation to be answered

More often than not, when the bull side of GBPUSD meets an unbreakable resistance, the bull side then retreats ( make a retracement, degree varied, from a few points to few ten points). After the retracement, the bull side moves up again. when the bull side meets the resistance again, it usually breaks it with ease. How come it's difficult to break at the first time but easy at the second time ? Is there anyone who has this observation before and who knows what happened behind ?

Probably the ones who placed an order from the beginning of the trend want to lock their profits which causes a retracement. Many of traders know that after a big/medium movement there will be a retracement and when the price hit a resistance line they place a sell order. Regarding the breaking of support/resistance, it's not necessarily to happen. It can test and retest that line for 2-3-4 times until a major break happens.

Ableman,

It has to do with many factors:

(1) How price is traded between banks.
(2) How strong the resistance is i.e what time frame your looking at.
(3) What the overall trend is.
