What is my AI Trading Architecture

-





Trading across multiple asset classes and international markets can quickly turn into operational chaos if you don't have a structured system in place. Between managing different base currencies, tracking disparate order fills, and keeping an eye on open risk, manual record-keeping is often the first thing to break.

To keep my process lean and repeatable, I use a modular stack of specialized tools tailored to specific markets—tied together by an agentic central hub.

The Trading Platform: Chosen for Specific Jobs

Rather than trying to force a single brokerage or software to handle everything, I segment my tools based on where they excel:

  • Moomoo (US Equities): Dedicated exclusively to trading the US market. Its liquidity, extended trading hours access, and competitive transaction costs make it my default choice for US equities.

  • Tiger Brokers (Hong Kong Equities): Dedicated to the Hong Kong market. I deliberately segregate my US and HK trading across two separate brokers for two reasons:

    1. Clean Currency Accounting: Keeping USD and HKD activities strictly partitioned simplifies realized foreign exchange (FX) calculations and avoids currency conversion slippage inside a single account.

    2. Platform Risk Diversification: Broker outages and maintenance windows happen. It also ensures, should there's some unforeseen issue with one broker, at least I still have access to my other portfolios- albeit in different market. 

  • TradingView (Market Scanning & Technical Screeners): While TradingView is widely regarded for its charting interface, its primary utility in my setup is its multi-timeframe scanner. It continuously filters down efficiently thousands of global instruments into an actionable watchlist based on volume surges, momentum divergence, and volatility metrics.

  • Kraken (Crypto / Digital Assets): My dedicated gateway for trading cryptocurrencies denominated in USD. It provides deep spot order book liquidity, reliable API uptime, and isolated collateral management away from traditional brokerage accounts.

  • Google Sheets (The Single Source of Truth): The operational backbone of everything I do. Platform-specific dashboards show only fragmented snapshots of your net worth. Google Sheets acts as my unified ledger: every order execution, fee schedule, open position, and closed-trade performance metric lives in one structured environment.

The Central Orchestrator: Google Antigravity

The missing link in multi-broker setups has always been inter-platform connectivity—brokers operate in closed silos, and bridging them traditionally required writing and maintaining fragile custom middleware.

Connecting all of these pieces together is Google Antigravity.

Acting as the central command center, Antigravity allows me to trigger trades directly from one place, dispatching execution orders straight to Moomoo, Tiger Brokers, and Kraken. I also use it alongside Moomoo and TradingView to backtest my trading strategies.

Finally, I configured and trained Antigravity to automatically log every executed trade into Google Sheets, structured exactly to my custom template. Once the raw transaction data lands in Sheets, I let Gemini take over to run performance analytics, sector exposure breakdowns, and P/L calculations within the Sheet.

How I Got Into Trading—and Why AI is Indispensable Now

-

I have been investing and trading ever since I was in university many years ago. I have always blended the two—investing and trading. What is the difference? That is for another blog. In the beginning, at least where I live in Singapore, buying and selling stocks was an expensive affair because of the high fees involved to complete each transaction. There were few brokers on the market, and most were somewhat linked to a bank—DBS Vickers, UOB Kay Hian, and Phillip Capital, just to name a few. The costs often included exorbitant fixed fees and variable fees. Coupled with the fact that I was a poor student and new to the job market, it was little wonder that I was not very active in the stock market. Gradually over the years, more products launched with lower fees—particularly those cash accounts where you lock in your money with the broker to enjoy lower fees. I remember I could trade with a US-based broker to enjoy really low fees, particularly on US stock transactions. I used TD Ameri...

Can AI Make You a Better Trader? Here’s How It Handles My Daily Grind

There are many moving parts, daily routines, and records I maintain to trade successfully. 1. Research & Analysis For me, research is often the most mundane part of investing and trading. Don't we all just want to jump straight into the action—buy and sell stocks and feel the adrenaline rush? The biggest challenge in finding the right stocks to buy is the sheer volume of data: there is simply too much news and too much noise to make quick, well-informed decisions. Over the years, I have learned to filter out what I don't need and focus only on what matters. I broadly categorize this information into three categories: market sentiment,  fundamentals and   technicals analysis. I start the day by gauging the overall market sentiment, then I start going deeper and precise by using fundamentals and technical analysis of the stock to buy. Sentiment of the Market I primarily trade the US markets. Between the Nasdaq and the NYSE alone, there are over 5,000 exchange-listed stocks. ...
