The same patterns that happen on a 100 tick chart are the same patterns that take place on a 10000 tick chart. Just charts that small don't give the human brain time enough to think and execute properly. Any sizable move makes the 100 tick chart to appear sporadic, when really the cycle of the pattern is just being sped up.
###################################################### Good question; % is a better measure. S/R is an area, a speed bump, a low fence. NOT even all 50 day moving averages are the same,[simple,+ weighted, EMA......]. NO ,one tic is noise, not s/r. Volume is not useless, one share of SPY, may not mean as much, as a 258 million SPY day in NOV. Every share counts; i mostly agree with your volume comments,Scataphagos.
