Bitcoin- Bulls need to maintain 42500 intact

Although I'm holding a buy position at this moment on BtcUsd, one thing is clear in my mind, I speculate on a correction to the overall trend, which is down.

Yesterday, as expected, Bitcoin has broken above 42500 resistance and looks like it wants to challenge 46k important one.
As long as 42500 is intact I will maintain my bullish bias and speculators can search to buy on weakness.
On the other hand, a daily close under 42500 zone will signal that the correction is over and Bitcoin can dive even under 40k this time
