Timing is everything! How long does a trend take?

Hi to all!

Everything in life is about timing!

I am a newbie trader and learned a lot in this forum for the last couple of months! Thank you to all!

But what I was really missing was 'how to time my trade'!
When to exit a trade!?

A trending market is going up and down!

What would be a reasonable TP and SL on each currency and on each time frame? What do you think?

Please help me to fill out my attached Excel sheet!

How long will a trend take? e.g. EURUSD 1M?!?

e.g.

EU 1M:
TP1=10
TP2=15
TP3=18
SL=8

EU 1H:
TP1=25
TP2=30
TP3=45
SL= 25

GU 1M:
TP1=10
TP2=15
TP3=18
SL=15

GU 1H:
TP1=30
TP2=50
TP3=80
SL= 30

So who can help to make an helpful tool for all of us?

I know that this is very complex and depends on many things e.g. system, etc.

But please help so others can profit from your knowledge!

P.S.: I post it in this thread because I believe that it is also a kind of system what you can expect from the market moves!

Maybe this explains what I mean!

I suggest you start looking into time relationships in the markets. Trading is a function of both time and price.

Here's a hint: look at the waves and find a way to measure them.

@Dopey: Do you know an indicator for that issue?

I will have a closer look at wave theory, thanks!

Anyone has a tool to automatically measure waves?
