Hiraeia (Piano Improvisation)

A rather peaceful but bittersweet melody that I played out randomly a few nights ago.  It's the longest piano improvisation I've made ever and after almost a year's hiatus, but I think it's my favorite piano composition so far.  I forget how nice it feels to really just flush your thoughts out over piano, and it's been a long time.

Tech Trader and Its 700% Trade on SPY

A monstrous week for Tech Trader for those following it on The Tech Trader Wall - first calling the exact bottom of SPY at $187 (on a daily close basis) and then holding call options through until $199, while actually fighting my attempts to sell the calls it bought by rebuying after I try to sell (and it turned out to be right to hold).  Again, all this on Tech Trader's part is fully automated, including the options trading, strike selection, everything.  The only part not automated was me trying to manage risk and actually costing Tech Trader an extra 200% in gains, to which it rightfully tried to get back by rebuying into calls that then went up 50% in the same day.  Looks like I no longer have a role here.

An excerpt from today's summary on The Tech Trader Wall:

Quote
And that's the end of Tech Trader's once-in-a-blue-moon 100% hitrate SPY signal.
6.5% on the equity from $187 to $199
200% on the initial weekly 191 calls from $1.5 to $4.5
700% on the roll to weekly 197 calls from $.3 to $2.12 (my bad for selling early, would have been $3 if I let Tech Trader do this, sorry Tech Trader)
57% on the 197.5 calls Tech Trader rebought this morning in disagreement to my selling from $1.47 to $2.32
160% on the month-out 191 calls that Tech Trader bought and held the whole time as a baseline return from $3.93 to 10.23.

I think I might have to step down here after costing Tech Trader 200% on potential gains lol.  There was actually a funny moment today where I literally couldn't sell because something in Tech Trader was blocking my order.  Now we know why.  I'm officially unneeded.

pq Visitor Counter and Tracker - Improved Spam and Bot Detection

The pq Visitor Counter and Tracker is an old but useful script, which has been integral in helping me keep track of what users are seeing on the site and cutting out spam/bots who are being more of a nuisance.  Its primary functions are as a unique visitor and view counter, but because it is virtually part of every page on the site, it comes in very handy as well for controlling entry points to the site, seeing malicious activity as they happen, and creating filters to block less friendly users based on the pattern of their activity.  This filtering then subsequently lends itself to cleaner analytics and understanding of how many real users you have and what their activities are.

I've spent the last few days adding new methods to tracking spam and bots so as to shut them down early if they're malicious and track/filter them out from being treated as human (for visitor counting, comments, etc) if they're crawlers.  I've also improved the look of the tracker page, so it's easier to identify between human, bot, and spam.  Bots are highlighted in a light shade of green now, with their user agents or other identifying factors similarly highlighted.  Spam is struck out in red to indicate they are being shut down on your site and definitely counted into your hits.  See the below screenshot or go straight to the visitor counter's demo to play around with it yourself.

The Return of Tech Trader

Been keeping Tech Trader somewhat under wraps the last few years.  A lot of the discussions and open projects I used to have here pretty much went silent or offline.  I'm gradually dusting off a lot of things I previously had online.


Tech Trader
A Fully Autonomous System Taking on the Stock Market

If it's been too long to remember what Tech Trader is, it's basically a program I built that now trades the same way I used to (or arguably better now actually than I ever did).  It's not quant.  It's not stat-arb.  The closest way to picture it is taking the kind of AI scripts I used to make for computer games and making one to mimic my actions in the stock market.  It's been running for the last 3 years now fully automated.

Some cool updates:
- Tech Trader's home page is now www.techtrader.ai
- The chat/discussion page for trading around Tech Trader is back, aka The Tech Trader Wall.
- Still trading on the Virtual Trading System (of course, that's just a toy compared to what it's been really doing behind the scenes)

I've had my share of hostility from being too open on these kinds of projects, so I'll play things by ear here to see how much I want to share again.
