Hi @Dazed&confused I note the reply from @48&34 also - I'm a very short term trader and I always use a chart based system, sometimes it's as simple as selling above the last high or close or a much better preferred system of "beating" the last breakdown bar. If I've beaten one resistance level then I tend to put an offer in one pip below the next resistance.
It's surprising how many times I get the daily high and usually don't give much away, although that has happened. Whatever you use try not to change it ---- I'm seriously guilty of this on Friday, I had a trailing sell on JAT at at 91 to be triggered if it fell one pip, which it did. but I cancelled the sell and have held over the weekend. If I get away with this one then it's worked. If I don't then a lesson will be learnt.
For longer term holds I do use resistance/support levels but also go back to more traditional ways such as the RSI and regression indicators in conjunction with VSA.
