USDCHF - What To Do After A Huge Breakout

Updated
We had a huge breakout of the main channel on the 4 hour chart, and it's been dropping more and more.
So what's a trader to do, jump on board and hope it keeps falling? Or grab a buy thinking it has gone far enough, and hope you were right?

It helps to know where we're at and where the structure is headed, take a look.

PS - The answer to the questions above is neither, hope you know that by now :)
Note
Looking good so far, we're headed towards the end of wave B any moment. Notice the double bottom right at wave A, so we're looking for a reversal pattern or something to indicate the start of C.
