There's a big difference worth discovery,imo stargate. Though the S/D zone lines do essentially become levels of S&R, there's a difference in location of the S/D zone parameters over the S&R lines overall. I'm finding that the S&R lines still apply, but the S/D zones are more trustworthy than any indicator on my chart. These are high odd areas (or zones) of reversal. Take the time, if you can find it, to really get a good applicable and working knowledge of what the zones are and how to locate them. You still have to trade with conservative lot sizes and the price can blow right through a zone, but there are definite stop loss points and high odd targets to be found. Not to preach, but these zones are giving me a lot more confidence in taking and holding my positions now.
