As for the "modern English", we're getting on a hundred years now since Wyckoff was plying his trade, and a lot of fans have added their own interpretations of his work over the years. If you go back to his original work, you won't find the jargon, the indicators, the exclusionary complexity. What you find is an extraordinary focus on the truth, i.e., how the law of supply and demand is illustrated in price and volume as a result of trader behavior, i.e., the participants in an auction market. Everything else is secondary. Or Tertiary. Or even completely irrelevant.
I'll grant you that Wyckoff is not exactly a model of simplicity, and there are a number of aspects of his approach which I don't think are especially necessary. Of course, it's not up to me to declare that they're useless, but I've studied his material with a focus on what I believe is the core of it, i.e., illuminating the demand/supply dynamic. Everything else is, to me, just noise, though it may not be noise at all to somebody else. To revert to complexity by adopting a new jargon set, as well as indicators and patterns (neither of which he could stand), wouldn't make much sense to me.
As for gaps, I've looked at all sorts of statisitcs and methods and tactics and strategies and none of it's really amounted to much. Everybody expects the PDC, for example, to provide S or R of some sort, so everybody expects the price to visit that level. I'm more interested in what happens if it doesn't, and the only guide I have is what's happening with price and volume. And by focusing on PV, you don't have to get into a lot of here's what you do with a breakaway gap and here's what you do with an exhaustion gap and here's what you do with a continuation gap blah blah. Ridding oneself of his preconceptions may be more difficult than memorizing a truckload of tactics depending on how he has classified a particular gap, but it's the only thing that makes sense to me.
As for candles, I think Wyckoff would have loved them. But who knows?
