setting stops is a risky business.. hehehe.. risk.. that's what it's all about.

But technically speaking, if a cut below support level is too deep a value, I'd recommend looking for a short term trend line. otherwise a previous low that holds for at least 2 days can also be used. Again, I would like to remind you that support and resistances with in periods of consolidation can or cannot be retested. when the price is moving sideways, anything goes. It is our recommendation therefore to stay on the sidelines when this happens.
During trending situations, its very easy to plot an accelerated trend line and any violation of that is worthy of stops. a trending support line is usually used for trailing stops.
Hope I was able to help.
