The thing about technical analysis is its just a tool.
Say you need to do a task. there might be 1000 different ways to do said task. Some ways work well in one instance, but not well at other times.
A different technique might work well when the other one didn't and vice versa.
Its the same with TA. There are 1000's of profitable ways to trade. You just need to pick one and stick with it long enough, while managing risk in order to see the results.
If you keep changing, or adding different types of analysis you will end up confusing yourself with comflicting information, and you will never be able to realise the absolute edge you have over the market from executing said strategy.
A second example.
System one (analysis, tools, technique etc) might win the following.
1. Win
2. Win
3. Loss
4. Loss
5. Loss
6. Win
System 2, different tools, analysis taking the same trades might be something like this.
1. Loss
2. Loss
3. Win
4. Win
5. Win
6. Loss
If you switched from system 1 to 2 and back to one again randomly, you will most likely catch all the losers. You will never be able to pin-point what part of your trading is wrong, since you are never trading consistently.
edit: just wanted to add, this is why everybody says there is no golden rule or technique to trading which is always right, so stop searching for it.
It is human nature to want to be right all the time, after all that is what applies to everything else in your life, however its not the case in trading. You must accept that you don't always have to be right in order to make money. Just be as logic as possible about it and use a trading plan.
Make a trading plan utilising a strategy(s) and stick with it. Trail for a large number of trades, assess results, adjust plan if necessary by reviewing your trades until desired results are achieved.
But what if your result depends not on the instrument, but on the movement of the market? For example, if market moves the way it used to, your outcome is :
1. Win
2. Win
3. Loss
4. Loss
5. Loss
6. Win
You are happy, go on sticking with this instrument, but suddenly market goes all around and that same instrument now shows this:
1. Loss
2. Loss
3. Win
4. Win
5. Win
6. Loss
So what's the use in having an instrument if it depends on the market movement which is almost impossible to predict?
