I had drafted a response to this post yesterday, but before I hit "send", I accidentally deleted my whole response. I was demoralized in drafting my response again at that time, but I have regained some typing enthusiasm, so let me try again.
Of course a 30% or even more BTC price correction could come at any time, and I doubt that your drawing squiggly lines on a chart, Retina, helps very much to inform us as to either when such 30% might occur and how much of a BTC price correction will come, once the correction gets started.
I have postulated on several occasions that 30% plus price corrections are quite common in BTC's dynamics, but also I believe that they are more likely to occur after the price has run for a while, rather than now when it seems that BTC might be on the cusp of pulling itself out of the bearishness of the longer down cycle that stared in December 2017 and was exacerbated (or even confirmed as either tragic or over) in November 2018.
So in earlier posts, including a post that came on April 1, just before this most recent price pumpening to $5k, I had already postulated that a 30% or more BTC price correction becomes more likely once we had reached over $5k (and surly we reached $5k way quicker than most of us expected, including yours truly).
A 30% or more price correction from our current local top of $5,345 would bring BTC prices into a $3,742 or lower range, which I would consider pretty whipsawing unlikely and even extra bearish to happen right now when a certain amount of upwards price momentum seems to have come out of the April 1 and since pumpenings.
Seems to me that getting to the $6,200 to $6,500 price range before experiencing a 30% plus correction would not be out of the question and even seems to have some possible credence now.. even while we have gotten temporarily paused in this $4,900 to $5,150 price range
In other words, I would expect at least a bit more UP before a 30% or more price correction becomes more feasible... even while nothing is totally out of the question in bitcoinlandia, some scenarios remain more plausible than others.. and the current short term momentum seems slightly UP even though I remain of the current opinion too, that we have not quite exited out of the bear market, just yet... getting close to exiting our current on the cusp bear market but I remain too conservative (in my lagging indicator perspective) to presume that the current local bottom of $3,122 is assured as "in" . Call me a whimpster.
