I am not going to give the secret away: it took me too long for that. But think multi-timeframe. My options trading was trading in 5 dimensions: the greeks.
Oh sure ... I thought it's some well known term, but couldn't find online. My guess was Price+Time+Volume+Cycle
I don't use volume, it's a way overrated looking at that in charts imho. I use one trendfollowing indicator and one oscillator on all 4 tf's.
I think so idd ... I have an algorythm that I use but I don't think it's programmable in the strictest sense. Part of it is applying after staring for over 10.000 hours at charts.
Some systems can't be backtested, like backtesting mercury moving on a flat glass plate when the wind blows.
Everything you typed above is patently false or misleading, except the transaction cost thing. That is a given. The rest are great in theory, but do not bear themselves out here in the real world.
good attempt to tell us what you think / feel about swing trading. For me, it is just the reverse. day trading is much better than swing trading. I hate swing trading. Swing trading is like taking one step forward, and multi steps backward. anyway, if swing trading works for you, by all means do continue using it.
