In this site we prefer the automated trading, but we are aware of its drawbacks (see e.g. this site). Therefore before we enter a trade we analyse the price plots to make sure that the signal really makes sense.
In addition, to further diversify, we enjoy the traditional trading by analysing plots visually and search for entries there (trendlines, support and resistance lines, price action). This will also gives us oppurtunities that our (and perhaps any) computer codes cannot find. Nevertheless, these entries cannot be backtested.
These ideas we have recently started to share (for free) at the TradingView site, see our profile there (right now we have not managed to publish many ideas yet, but we hope to populate the list gradually). We do not limit our entries solely to stocks, but also to ETFs, commodities and currencies.
