How did our Futures Trading Algo Do Today?
Discipline
Sitting out a day with no qualifying setup is still a disciplined result.
Our automated paper book stayed flat today on NQ and ES, with zero trades taken and no wins or losses. The market gapped and ran hard in one direction, and none of our rule-based setups met their entry conditions, so the book waited instead of chasing. Net result for the day: $0.

The story
US stocks ended sharply higher on Monday as renewed optimism around artificial intelligence and a pullback in Treasury yields lifted buyers across the market. The Nasdaq 100 surged 3.94% to close at 30,781, and the S&P 500 gained 2.24% to finish at 7,829.25. Motley Fool reported that tech strength powered the Nasdaq to a record close. Falling yields eased pressure on growth stocks, and a dip in oil prices added to the relief.
The MAG7 and the megacaps
Big technology names were at the center of the move, which is why the Nasdaq 100 outpaced the S&P 500 by a wide margin. With AI optimism back in focus, the largest tech companies helped drive the record Nasdaq close. We do not have individual stock moves in today's data, so check your own watchlist for specific names.
After the bell
AI optimism reignites
Reuters reported that Wall Street ended sharply higher as enthusiasm for AI returned. Tech shares led the gains, and the Nasdaq 100 closed at a record.
Treasury yields retreat
Lower Treasury yields made stocks more attractive relative to bonds and eased pressure on growth companies, whose future earnings are worth more when rates fall.
Oil dips to $100 on diplomacy hopes
Reuters said oil slipped to $100 on hopes of US-Iran diplomacy and a partial recovery in Saudi exports. Lower energy costs can ease inflation worries.
Geopolitics stay in focus
Reuters coverage pointed to ongoing Iran-US tensions and pressure on LNG supply. Headlines here can move energy prices and market mood quickly.
Crypto
Bitcoin joined the risk-on move, rising 6.74% to close near $86,608. It traded between roughly $80,933 and $87,281 during the session, a wide range that shows how sharp the swings were. Crypto often rises when investors feel more confident about risk assets, and today fit that pattern.
Into the night
Futures were volatile, with the Nasdaq 100 futures contract trading between 29,904 and 30,862.75 and S&P 500 futures between 7,713.75 and 7,847.25. Both markets finished near their highs of the day, showing buyers stayed in control into the close.
What is coming next
Nasdaq 100 high
30,862.75
Today's high is the level buyers will try to hold or extend.
Nasdaq 100 low
29,904
Today's low marks where sellers were absorbed.
S&P 500 high
7,847.25
A move above this would extend today's breakout.
S&P 500 low
7,713.75
Holding above this keeps the rally structure intact.
After a move this large, markets often pause or pull back before choosing a direction. Watch whether yields keep easing and whether oil stays near $100, since both helped drive today's rally. This is educational information, not financial advice.
