I need to broaden my portfolio, do not expect to trade daily, What/who do you use for monitoring several exchanges and instruments? Even a simple program?

Moneydance handles all my finances.

If you trade in the U.S. stock market, I can highly recommend the Motley Fool Stock Advisor newsletter. It's a paid subscription but worth it. Over the past few years when a lot of people have lost all their stock holdings, my money has nearly tripled. Now I've subscribed to a second newsletter, Motley Fool Options. This one is even more costly but I'm getting great advice in trading options which is a way to reduce risk in stock trades while booking monthly income. I made my first options trade this week.

I know this isn't exactly what you asked, but still it's a nugget worth sharing. And no, I'm not a paid spokesman for Motley Fool. :-)

I use Yahoo Finance for monitoring a portfolio of UK and US stock, but it does not work with SET

Google

Zacks.com and seekingalpha.com let you build and monitor portfolios free, but only US stocks.

Google finance, advfn.com, https://baby.boom.com.hk/en/

Excel

bloomberg.com is the best free monitoring service out there- for ALL markets- you can also do free basic technical analysis.

I invest, I dont trade, so i enter my holdings into free web-site portfolios. Yahoo for US and Moneyextra for UK. If anyone knows of a SET equivalent in English that would be good to know.

Traders should probably pay for something more professoional and less delayed than that - eg Interactive Investor or Bloomberg
