Last Feb. I was hearing quite a bit about the free and uber low cost brokerages starting up, including Sogo Invest, Zecco, and Just2Trade, and a change to free at Bank of America for accounts over $25,000 (note: Wells Fargo recently started offering free accounts too).  I dismissed Bank of America because they aren’t offering any interest on cash. 

Now, I’m not sure whether free trades will turn out to be a fad, and Scottrade trades are already a low $7.  Yet, the appeal of free is that I can make small trades without guilt.  For example, if I want to place a bet of $1000 on a very speculative stock, at Scottrade the buy and sell will eat 1.4%.  Which is why I don’t usually make trades that small on my Scottrade account.  Anyways, I thought I’d give one of these free trade brokerages a try.  Below is my original homework… 

	Sogo Invest	Zecco	Just2Trade
Cash Interest (MM)	2%	1% (4.35% MM)	(4.44% MM)
Trade Cost	$3	$0	$2.50
Min Investment	$0	$2500	?
Services Not Free		$50 ACAT out $30/yr checking	$50 ACAT out
Funding Method	ACH	ACH	?
Free	Email statements Account closing ACAT (both)	Email Statements Account Closing ACAT in	Checking
Thoughts	Backed by big trading house	Sketchy business model Concerns about paperwork	No ACH yet Crappy website

My original notes 02-28-2007

Went with Zecco…because it seemed like the most likely to reach maturity of the three.  And the 40 free trades a month.  The process of getting a Zecco account is crude (you’ll understand if you try it), as is much of the website.  Particularly annoying is that certain tasks require re-entering your password even when logged in.  That said, I’m actually very happy with the service.  Although Scottrade is still my primary brokerage, I now make most of my short-term trades in the Zecco account.  I’ve put far more money into my Zecco account originally planned.  The things that matter most to me–trade execution and cash interest–are great.

Bottom line: I’m not sure whether Zecco’s business model will stand the test of time, but right now I’m a happy client.

CSV (comma separated values) Parsing

The data is returned in a csv file. As WordPress plugins are written in PHP, the built-in function fgetcsv (http://us3.php.net/fgetcsv) will work nicely.

<?php
$fp = fopen (“http://quote.yahoo.com/d/quotes.csv?s=goog&d=t&f=svl1&e=.csv”,”r”);
$stockData= fgetcsv ($fp, 1000, “,”)
?>

symbol: <?php echo $data[0] ?>
volume: <?php echo $data[1] ?>
last price: <?php echo $data[2] ?>

<?php
fclose ($fp);
?> 

Less useful, but worth pointing out, is Yahoo ICharts, which are thumbnail charts that may be directly referenced. Examples:

In the meantime, the three plugins I’m aware of are below. The first two were created by Andrew Hill, the third by Patrick Chia.

1. Stock Quote Tooltip
This is quite nicely done. Also links to Yahoo finance, which is a nice touch. Just mouse over GOOG to see it in action.

2. Stock Quote Sidebar
Creates a list of stock quotes. Might be useful for posting a portfolio or basket.

3. Stock Chart Widget
