So I'm fairly new to TA and have a couple questions. First, it seems that TA is fairly subjective as I can almost make any chart look the way I want by messing with the params (e.g. changing the MA length, etc.). What I'm looking at now is Gold (well, I'm looking at the GLD ETF stock). When I have it at 10 days, hourly view, the stock looks quite bullish as the 25 hour MA just crossed over the 75 hour and the 50 hour crossed bullishly just afterwards. However, if I pull back to 1 month with a daily view, the 25 day MA just crossed bearishly over both the 50 and 75 day MA. Which is more telling of the security? Should I assume that the bearish signal is longer term while the bullish signal is shorter term, but can become longer term? Thanks!
