Skype backer takes on ETrade with free trades

Filed under: finance — michaelangela @ 4:23 am

Whoa… hmm… wow… you know with other companies charging $7 – $10 just to make a trade it’s so expensive just to be involved. But this makes it available to regular folks much more easily. Will they survive? No one can tell at this point. But it’s interesting nonetheless. Still, the problem is raising the money to invest in the first place…

Skype backer takes on ETrade with free trades:

Morten Lund1, the guy who was the earliest backers of Skype is at it again. He has financed Zecco2, a start-up that will allow consumers to trade stocks for zero commissions, versus $10 to $20 that many online brokers charge today.

Willow Solutions, Inc. – Back Testing a Trading Strategy with a Dynamic Moving Average

Filed under: finance — michaelangela @ 11:29 am

This is part of the quest to understand how people earn with the stock market using trend following techniques. It’s harder to actually earn the cash for the investing though! But… one step at a time. So this is about using using Excel to create charts for Exponential Moving Averages. This came about as we were learning about Simple Moving Averages. Exponential Moving Averages track the price closer than Simple Moving Averages.

Why go through all of this? It’s about trends. Of course with stocks and funds, etc., you want to “buy low, sell high”. But it’s almost impossible to know how to predict when to do that. So don’t predict, follow what the market is actually doing. That’s why these are trend following solutions.

One very cool tools are the new interactive Yahoo! Finance charts. They are fun to play with but can be CPU intensive. This example shows the performance of the Dow Jones and the S&P 500 over the past year. Very impressive growth… to me at least. Over 10% for both of them. Another interactive chart is from StockCharts. It is Java based so you need to have Java installed. But it’s fast as well, though it doesn’t have the other indicators on the chart itself. But it’s very useful nevertheless. This is a comparison chart between the S&P 500 and the Dow Jones.

Both show the overall gist though. There have been tremendous gains. More quickly visible on the Stock Charts graphs (by dragging the slider at the bottom all the way to the left) is the huge drop beginning in 2000 and ending around early 2003. That must have been painful, especially if you were using a buy and hold strategy. If you were using trend following, and you were following relatively closely, you would have lost some money. But, on every upswing, you would have made good gains. So that’s the trick: catch it on the upswing. Sell on the downswing, but early enough to catch it. It’s not as easy as it sounds though as there are “whipsaws”, rapid oscillations which could trigger unnecessary activity. If not tracked correctly, i.e. a good time frame for that actual investment, be it stock or mutual fund, you could lose more money as well. So it’s all a trade off.

That’s what leads to this post: Back Testing. Taking an idea an test it on historical data. Have to see how hard that is to do… Well nothing free and easy! 🙂

Willow Solutions, Inc. – Back Testing a Trading Strategy with a Dynamic Moving Average:

In this Willow Tip we are going to discuss how to add a dynamic moving average to a stock price chart which displays the high, low and close. You create a dynamic moving average by creating within the formula a reference to a single cell. This single cell holds the number of days for the moving average. Once this is done the moving average will recalculate when you change the value in a single cell e.g. from a 30 day moving average to a 20 day moving. The moving average on the chart will adjust accordingly. This lets you visually see how often the moving average is crossed and when a buy or sell signal is generated.

Top JavaScript and AJAX Libraries

Filed under: ajax, web20, widgets — michaelangela @ 8:46 am

I wouldn’t say it’s all the libraries needed, but it is a good list with some extras I hadn’t seen before.

Top JavaScript and AJAX Libraries:

On this page you’ll find all the JavaScript and AJAX libraries you need for your website and web application development, ranging from single-purpose scripts and script depositories to entire JavaScript application frameworks.

The Top JavaScript and AJAX Libraries list is compiled, rated and maintained by JavaScriptDeveloper.com.

In evaluating the libraries the following properties are take into account: the ease-of-use, documentation, suitability to the task, cross-browser compatibility, demos and examples, flexibility and extensibility.

Small libraries that are perfect for the task in one category are rated better than large libraries that do an average job in multiple categories. Likewise, there are many libraries that simplify AJAX development – but without offering additional benefits they cannot be awarded the top rating.
