【Nov 6｜Drive30】Nikkei average drops 3,643 yen in historic plunge! Even so, post-judgment is NONE｜Even in a big market, we don’t change the rules
November 6, 2026 (Friday) ｜ Daily Market Report
Nikkei Stock Average declines by 3,643 yen.
On a day of historic sharp drops
Drive30 is postponed.
In the Tokyo stock market on November 6, the Nikkei Stock Average fell by 3,643.13 points from the previous day, triggering a sharp drop.
The Nikkei Average fell well below 60,000 yen, dropping to the 56,000s at one point. The decline was the third-largest ever in terms of magnitude.
On such a day with such movement, what judgment will Drive30 show?
From saved data, we conducted a retrospective verification using fixed rules.
Today’s retrospective reference judgment
Retrospective verification hypothetical trades
Theoretical profit/loss of retrospective verification
This is a retrospective calculation from stored market data.
This is not a record of real-time performance for the day.
01｜Nikkei Average’s historic drop
On November 6, the Nikkei Stock Average fell 3,643.13 points from the previous day, marking five consecutive trading sessions of decline.
Due to a large drop in the US market the previous day, AI and semiconductor-related stocks fell significantly, leading to broad selling across many stocks in the Tokyo market as well.
The TOPIX also fell sharply, resulting in a broad-based decline across the market, not limited to any specific stocks.
02｜Drive30 morning retrospective judgment
In the morning observation window for the Nikkei 225 futures, there was large volatility in both directions.
Checking the saved 1-minute bars, all 30 required bars existed and were confirmed.
Using this price data, a retrospective calculation with Drive30’s fixed rules yielded the following results.
SELL BIAS represents information suggesting a tendency toward a decline.
It does not by itself constitute a formal SELL signal.
03｜Even with a big drop, it doesn’t necessarily mean a sell signal
On days like today’s sharp fall, you might think, “If you had sold, you could have profited significantly.”
However, changing the morning trading decision after knowing the closing price would no longer be a verification under fixed rules.
A day when the market moves a lot
and a day when you trade according to your own rules
do not necessarily coincide.
Postponing trades does not necessarily mean it was the correct decision.
Even if there was price movement you could have captured, the fact that the conditions did not align is recorded as is.
Good results and bad results should be evaluated using the same standard.
