Three Days, One Bot: +$322, +$326, -$618

Three trading days. Same bot, same rules, same 9:32 AM entry window. By Thursday afternoon the scoreboard read: +$322, +$326, -$618. Net profit for the week: $30.

That number deserves to be looked at honestly. Two wins that felt routine. One loss that felt brutal. And at the end of it, a $30 profit that doesn’t even cover lunch. This is what consistent mechanical trading actually looks like — not a highlight reel, not a horror story, just the math running its course across three very different mornings.

Here’s what each day looked like from inside the tick log.

Tuesday, April 29 — The Textbook Day

SPX opened at $7,127.86 and the bot fired at 9:32 AM. Short strikes landed at 7165 on the call side and 7085 on the put side — an $80 corridor centered near the open price.

The first tick, one minute in, showed -4.1%. SPX had dipped to $7,123 almost immediately. For a second it looked like the put side might get tested.

It didn’t. SPX spent the next 50 minutes doing exactly what an Iron Condor needs it to do: absolutely nothing dramatic. It drifted gently between $7,120 and $7,138, slowly leaking premium out of the options. By 10:00 AM the position was at +21.9%. By 10:20 AM, +32.9%.

At 10:26 AM, SPX touched $7,137.65 and the profit target fired.

+$322. 54 minutes. Done.

There’s not much to say about days like this. The position never came close to the stop loss. The market stayed in range, theta did its work, the bot closed clean. It’s the kind of trade that makes the strategy look easy — which is exactly why you have to be careful about how you remember it when Thursday comes along.

Wednesday, April 30 — The Same Outcome, the Hard Way

SPX opened at $7,156.66 — about 30 points higher than Tuesday. The bot selected 7195 calls and 7115 puts, same 20-delta logic, same $100 wings.

The first few minutes were fine. Then at 9:36 AM, SPX dropped fast — from $7,158 to $7,147 in a single tick, taking the position from +4.1% to -16%. That was the opening act.

By 9:40 AM, SPX was at $7,141 and the position was at -28.9%. By 9:41 AM, -29.5%. The short put at 7115 was now only 26 points away. Not imminent danger, but the direction was wrong and the speed was uncomfortable.

Then SPX bounced. By 9:45 AM, +5.5%. Crisis averted — or so it seemed.

At 9:52 AM it started sliding again. This time it went further.

At 9:58 AM the position sat at -42.3% against a 50% stop loss. SPX was at $7,131 — only 16 points above the 7115 short put. One more bad minute and the stop fires.

One minute later, -22.5%.

The market had one more test left. At 10:09 AM, SPX dropped to $7,130 and the position hit -39.1% again. The short put held. And then — slowly, grinding, tick by tick — the position climbed back into profit.

By 10:30 AM it was at +21.8%. By 10:33 AM, +31.5%. At 10:46 AM the profit target fired.

+$326. 74 minutes. Same payout as Tuesday, completely different experience.

The thing about mechanical trading is that both of those days produce the same number in the spreadsheet. But anyone watching the tick log on Wednesday knows those two trades felt nothing alike.

Thursday, May 1 — When the Call Side Gets Run Over

SPX opened at $7,240.03 — up 83 points from Wednesday’s open, the biggest gap of the three days. The bot selected 7255 calls and 7205 puts.

That 7255 short call was only 15 points above the open price.

With $100 wings and a 20-delta setup, the bot is designed to handle normal opening volatility. But “normal” is relative. When SPX opens 83 points higher than the day before and keeps climbing, the short call strike that looked like a safe distance at 9:32 AM doesn’t stay safe for long.

By 9:34 AM — two minutes in — the position was already at -27.2%. SPX had moved from $7,240 to $7,245 and the call side was immediately under pressure.

The next 20 minutes were a slow grind between -20% and -35%, with SPX hovering in the $7,243–$7,250 range. The short call at 7255 was tantalizingly close. The position never found relief.

At 9:55 AM, the position was at -29.3%. SPX was at $7,250 — five points from the short call.

Then at 9:56 AM, SPX printed $7,257.84.

The short call at 7255 had been breached. The position went from -29.3% to -74% in a single tick. The stop loss fired.

-$618. 24 minutes.

The whole trade lasted less than half an hour. The stop loss did what it’s supposed to do — it capped the damage. Without it, the position could have deteriorated further as SPX continued climbing. But $618 is still $618.

The Week in Full

Three trades. Two wins. One loss. Thirty dollars.

This is the part that doesn’t make the highlight reels. The strategy worked exactly as designed on all three days — profit target on the wins, stop loss on the loss. No deviation, no discretion, no “let me just see what happens.” The bot ran its rules and the math produced $30 net.

Whether that’s a good result or a bad one depends entirely on what you expect from the strategy over a large enough sample. A single week tells you almost nothing about edge. What it does tell you is that the variability is real — and that the one stop loss trade can easily erase a week of wins.

May 1 stands out for a reason worth noting. The gap open to $7,240 placed the short call at 7255 only 15 points from spot. On a day where SPX was clearly in an uptrend from the bell, that proximity was the setup’s vulnerability. The delta selection was right by the numbers — 20 delta at the time of entry — but the direction of the open mattered enormously.

Tuesday and Wednesday both had short strikes 38–41 points from spot. Thursday had 15. That’s the same strategy producing three very different risk profiles, and the data captures it perfectly in the tick logs.

The bot doesn’t know any of that. It fires at 9:32 AM, selects the 20-delta strike, and runs the rules. Some mornings the market cooperates. Some mornings it doesn’t.

The week ended at +$30. The bot will be back Monday.
