Yes, you heard KOSPI in Korea market. Even the symbol A035720, at first line in above picture, can be received in NYSE too. As mentioned, many STILL use Excel, since Korea government recommend to use Active-X and MS Windows. Also I had rare experience in Excel before. It will take many days, to describe my logic. In short, I use the pattern that most daily candle shows that daily close is higher than daily low. But most of my own program is NOT Excel. Excel is just for data-receive and order execution, for each brokerage company API. Of course my own (main) program to find BUY point in each stock, with more than 1000 lines, is written without Excel.
You can use ET internal PM system to communicate with me otherwise, as Yahoo might put emails as SPAM, a pain
