Upgrading the Brawler System (Jan 12, 2026)

Like a zombie at Starbucks right when it opens at 07:00 on the weekend, I ordered an Coffee.

With the help of AI, I started testing the Alpha Logic of my Brawler System.

I am currently using this logic for the US stock market and want to see
if it works in the Korean market as well.

I already subscribed to the Google AI Pro 3-month discount plan for this.

KOSPI: A Familiar Face

The data for KOSPI stocks is well-organized, much like the US market data I usually analyze.

So, the testing went smoothly.

I used to wonder, "Are the US and Korean markets similar?" As expected, KOSPI stocks showed data and results that were quite similar to the US market. I can say,

"Okay, I understand how you move."

KOSDAQ: A Brutal Fight

The real challenge was KOSDAQ.

There wasn't as much data, and the results showed the system getting "beaten up" by the market quite often.

The numbers clearly said, "This market is not easy."

Just by looking at the backtesting results, I could feel the high difficulty of this market.

If something looked even slightly wrong, the Brawler Alpha Strategy suggested it was better to just stay out.

Having a stable performance is more important than having the highest returns.

Same Alpha Logic, Different Survival Ways

For KOSPI, I apply the Brawler Alpha Strategy almost as it is. It’s a "straight-on" style—taking some hits from the market but holding on to eventually take the profit.

KOSDAQ is different. It avoids trades when things look risky (about 1/3 more than KOSPI). It only takes hits and makes profits in the remaining 50% of the sections.

I’m not sure when I will go live with this yet, but I plan to continue backtesting through January.

From February, I will finalize the logic and start a pilot run. I’m thinking about the actual application sometime next year.

Instead of rushing, I’ll take my time every weekend morning at Starbucks with a cup of coffee to make the system stronger.

I want a "smarter" Brawler—one that knows when to take a hit and when to dodge, rather than just getting beaten up by the market.

My Old Laptop is Getting Tired

I use an old ThinkPad T530 for my Brawler System Trading People call it a "dinosaur" because it is so old. I keep it running 24 hours a day. It restarts itself every morning to stay fresh. What This Laptop Does This old friend works very hard for me: Korean Stock Market: It runs YesTrader from 09:00 to 15:30. US Stock Market: It handles trades from 16:00 to 05:00 the next day. It follows my rules and places orders all day and night. Signs of Aging Recently, the laptop has been acting up. The USB for my Arduino stops working. The CD drive causes the system to crash. Sometimes, it just turns off for no reason. But when I get home, I turn it off and back on. Then, it works perfectly again! I still trust it, but I did remove the CD drive to help it run better. Now, every time I press the power button, I pray it stays safe. It is running so smoothly that I've already forgotten about the previous errors. Looking Ahead I already have a backup laptop, a T580. Once the br...

장비도 같이 늙어가고 있습니다.

매매 주문을 하는 PC는 오래된 씽크패드 T530 입니다. 아주 오래된 노트북이라고 불리는데요. 24시간 켜두고 있습니다. 매일 새벽 스케줄에 따라 재부팅하며 한국주식시장의 주식 매매를 위해서 예스트레이더를 실행하여 09:00부터 15:30 까지 조건에 맞는 주문을 하는 친구입니다. 그리고 미국주식시장의 주식 매매를 위해서 16:00~다음날 05:00 까지 조건에 맞는 주문을 하는 친구입니다. 최근 노트북이 가끔씩 오류를 내고 있습니다. 연결해둔 아두이노 레오나르도의 USB 가 다운되며 안켜지고 CD롬 오류로 뜬금없이 다운되고 이유 없이 다운되고 있었는데요. 퇴근하고 완전히 껏다가 다시 켜면 쌩쌩하게 동작해서 다시 믿음을 줍니다. 이제는 방해가 되는 ODD CD롬도 빼버렸네요. 전원버튼을 누르며 안전하게 동작만 해달라고 기도하고 있습니다. 그리고 오류를 냈던 것을 잊을만큼 다시 생생하게 작동을 하고 있습니다. 백업용 노트북도 T580도 준비 해두었는데 증권사의 윈도우10 지원이 끝나면 이제는 이전해야겠습니다.
