What this site is
By WoozKa is an independent research desk covering money and economics, investing, stocks and ETFs, crypto, forex and futures, and trading systems. It is written for people who manage their own money and would rather understand a mechanism than be handed a conclusion.
It is written by Woo Joong, a trader and market researcher. Articles here start from primary sources β regulatory filings, exchange and broker documentation, central-bank data, published academic research β rather than from other blogs, and figures carry the date they were accurate as of, because finance content ages faster than almost anything else.
The house style is to show a method alongside the conditions under which it stops working. An approach that only ever appears in its best light is being sold, not explained.
What this site does not do
- No personalized advice. Nothing here accounts for your circumstances, and none of it is a recommendation to buy or sell a specific investment.
- No signals, no courses, no “system” for sale. The tools are free and run in your browser.
- No original backtest results presented as evidence. Where backtesting comes up, the article explains the methodology and its pitfalls and points to published research, rather than asking you to trust numbers you cannot audit.
- No pretending about AI. Drafting and research organization are AI-assisted; a person reviews, fact-checks and finishes the work, and is accountable for it. Personal experiences described on this site are real, not generated.
- No paid conclusions. Some pages mention brokers or products and some links are affiliate links. They are disclosed, and they are never the reason a conclusion is what it is.
