After I have identified a fundamental stock, I use charting and basic technical analysis to decide on my entry points. Every stock to me has a trading range and I rather buy at the bottom of the trading range.
For stock quotes, I use a few of our local brokers' trading platforms as these have certainly improved significantly over the years. Also, many of brokers provide multi market quotes and as time goes by, I may be expanding my horizons beyond just Singapore stocks.
Of course, more importantly, I don't have to pay for these tools.
