Expiry Thursday on the SENSEX is the day most retail traders remember for the wrong reasons. Today we are one of them. The machine took three trades on 10 September 2026 and finished the session down ₹26,200.
We publish the bad days the same way we publish the good ones. Here is exactly what happened, minute by minute.
| Time | Trade | Entry | Exit | Held | Result |
|---|---|---|---|---|---|
| 11:15 – 11:17 | 74700 CE | 242.70 | 220.70 | 2 min | −₹19,800 |
| 11:51 – 12:06 | 74700 CE | 203.75 | 213.75 | 15 min | +₹13,400 |
| 13:07 – 13:09 | 74800 PE | 161.90 | 139.90 | 2 min | −₹19,800 |
The machine marked a resistance level, waited for a confirmed break above it, and bought the 74700 call at 242.70. The break did not hold. Price came straight back through the level and the fixed stop-loss did its job at 220.70.
That is exactly 22.00 points of loss. Not 30, not 45. The stop distance is fixed before the trade is placed, so the size of the damage is decided while we are still calm — not while we are watching the screen go red.
Thirty-four minutes later the machine bought the same 74700 call again, this time at 203.75. Cheaper, because the first attempt had already bled the premium.
This one worked. The scale-out rule banked part of the position on the way up for ₹8,800, and the trailing floor carried the rest until it was taken out at 213.75 for another ₹4,600. Total: +₹13,400 in fifteen minutes.
After lunch the machine flipped side and bought the 74800 put at 161.90 on a downside break. Two minutes later the stop filled at 139.90. Again 22.00 points. Again −₹19,800.
Think of a T20 innings. A batsman who edges to slip for 4 has not necessarily played worse than one who edges to slip for 4 in the next over. Both got out. What decides the scoreboard is how many runs the partnership in between managed to put on before the next wicket fell.
Today our partnership put on ₹13,400 and we lost two wickets at ₹19,800 each. The arithmetic did not work. On a different day the same two wickets fall and the partnership runs to ₹40,000, and the day is green. The wicket size is the part we control; the partnership size is the part the market decides.
September so far, day by day, as recorded: −₹19,350 · +₹38,723 · +₹3,600 · +₹11,192 · +₹25,287 · −₹26,200. Month to date: +₹33,252.
Today was the single worst day of the month and it removed roughly 44% of what the month had built. That is not a footnote we want to bury. Six recorded sessions, two of them red, and a month that is still positive only because the green days were larger — not because the red days were rare.
We are not going to tell you the machine will make it back tomorrow. We do not know that. We are not going to tell you a filter would have avoided both losses — the second trade came from the exact same level as the first, so any filter that blocked the loss would very likely have blocked the winner too.
What we will keep doing is publishing the log. Three trades, two stops, one trail exit, −₹26,200. That is the day.
