How do YOU know when to take profits?

I've been trading for about 2 yrs.I've recently started trading the /dx.I found currencies are much more important and is a lot harder to find the right place to take profits compared to the emini.I've been using Fibo Retracements and Extensions to set targets.
I have to keep a pretty wide stop for currencies because of the volatility.I place my stop below the low of the previous day.With this strategy its even MORE important to find the right target otherwise a lot of profits slip.
My question is how do YOU know when to take profits and do you you have any suggestions for this new strategy?

In most cases 80-90% of ADR based on 30-60 days.

can you elaborate?

You don't. You just take whatever you want, and let a tiny bit run with the flow(if not countering). Repeat this 10-15 times and at the close of your session you have a swinger. Chop it off two 3rds and let the rest run overnight.
Next day continue from where you left of.

i used price action to determine where to take profit. I am a life long emini traders as well as fx eur/usd trader. As for the eur/usd 100K per contract, i look for 6 pips profit target intra day.

By having a plan BEFORE you enter the trade.

Is there an MT4 indicator that gives you the ADR for whatever period you enter?

If not, where does one go to get ADR's?

Average True Range in Oscillators in Mt4?
Otherwise I'm sure there would be plenty of custom ones just google it

Or you could just keep a spreadsheet

Spreadsheets? Yuck!

Spread sheets are sexy

When I think of taking profits, I think of pulling money out of the account. Is that what you mean?

To me that's like asking "when do you stop sex?".

It's about the movement, volume, and liquidity. I take profit when the move runs out of steam. Know what I'm sayin'?

Depends on the strategy. Mine personally is years from now.. or never

Yea, I get what you mean..

I personally take profit on a mechanical basis. 2x risk seems to work best for me. I'll close out all but 1 mini or micro lot at the target and let the last little bit run to see how far it will go. Sometimes the market will give me as much as 10x risk. Most often though I will get little more than break even + 1.

I have pre-defined target profit calculated from the average daily range based on the last 30 days. Then, I take 80-90% (depending on the currency since most pairs have their own "optimal set of values") of that range and plot it as target on intraday basis. Here's a chart of how it looks. Red price-tag represent 80% of the last 30 days average range on eur/usd;

Hi, I only entered into a trade on important news announcements, and have made fairly small but consistent profits . Its been a very slow progress and would be grateful for any advice from more experienced traders on this strategy.

I take partial exits at specific price points, then throw a trailing stop on the last open position. Otherwise, I let myself take small profits and big losses.
