AI Summary
Summary
The post showcases a comparison between an algorithmic trading strategy's backtest results and its live trading performance on the USD/JPY currency pair.
The author's thesis is that a correctly implemented backtest should closely mirror live trading results, and they provide their own performance as evidence. The author also notes a deviation from the backtest due to a discretionary decision to halt trading based on geopolitical news (an impending war).
Quality assessment: This is a personal anecdote about trading methodology rather than investment research or due diligence (DD). It's noise from an investment insight perspective, as it focuses on the process of algorithmic trading, not on a specific market forecast.

Just went to compare my recent USDJPY trades with the backtest. Almost identical! That's how it should be when you backtest correctly.
The last trade differs because I didn't trade USDJPY most of Feb 26 because I knew the war was close, and I decided to stop everything at 20:15 on that day. The war started 1.5 days later.
