If I were teaching a new trader (definitely make A LOT more) I would stress 2 things... Use S/R levels and Trendlines to GET in the current trend and REMOVE any levels ahead of you as once markets are traveling in a given direction ANY level can be broken (since the strength of a level is dependent on sentiment, which changes often).. especially slow, dull markets.
NQ 2117 WAS very important.. yet we just calmly swam by it...
Oh, another thing, S/R levels are actually "areas" that can expand at any time, usually enough to get your puny stop... Clear as mud?
