I'll throw my 2 cents into this pot.
I think the answer to the question starts with "what are your objectives"?
I've seen no reference to time frames here, or to trading style or time availability. So i'll proceed in a general manner.
If I'm trading for short term momentum moves that can go on from hours to days, I'll start by looking at a large hourly chart and asking myself "where is it going?". If it's going nowhere, then I might decide to stand aside or range trade it.
For simplicity let's look at EurGbp as it has recently offered a good example for our means. Taking our cue from the 4H chart, this week opened and found sellers around the rejection area from friday. Let's hypothesize you found an entry around there. Stop would be initially above the reaction highs.
then you could shift down a time frame and manage the trade via hourly lower highs/lower lows in a typical peak/trough manner...that way it's the market to tell you when to pull the plug on the trade.
An evident level to watch was last week's lows and that's where we got a reaction that would have taken the trailing stop.
This was only an example, but the main lesson i've been taught over the years is to be systematic in everything, including the way I manage the trades. If you do not manage the trade with the same structure each time, your trade records won't be able to tell you really what you're doing right or wrong because you won't be operating with a "structure".
Hope this makes sense...
