How to Build a Daily Bias for ES and NQ Before the Open

Taking longs and shorts at random is a problem you can fix before the open. A written daily bias will not tell you where ES goes, but it tells you which side you plan to favor and what would change your mind. That keeps a losing trade from rewriting your plan halfway through the morning.

What a bias is and is not

A bias is a lean, not a forecast. It decides which setups you look for first and which you skip unless something clear changes. I treat each input below as a hypothesis to check against my own records, not as a rule that works because someone said so. If you want to know whether a given input helps, log it and compare.

Four inputs

1. Overnight price action. Compare overnight trade with the prior day's close and look at the structure on a 15-minute chart: higher highs and higher lows, a grind lower, or a sideways range. Note the overnight high and low, since the early session often trades around them. Globex trading runs nearly around the clock, so decide which part you call overnight and use the same definition each day. The midnight ET price is a reference some traders use, but it is not the session open. Check CME's schedule for holiday sessions and early closes.

2. The prior day's character. Was yesterday a trend day or a rotation day? Mark the prior day high and low, since those levels get tested often. Whether a trend day continues or fades is not reliable, so treat yesterday's character as context, not a prediction.

3. Reference opens. Note where price sits relative to the monthly open, the weekly open, and the prior day close. Some traders find these useful as reference points. Others do not. If several of these sit on the same side of price, that is a cleaner picture than a mixed one, but it is only a picture. Track whether it actually changes your results.

4. Correlated markets and conditions. Before the open, look at the dollar index, the 10-year yield, VIX futures, and any scheduled economic releases. Relationships between these markets and equity futures shift over time, so use them for context rather than as a signal. One note on fair value: the gap between index futures and cash is mostly carry (interest and dividends), so a premium or discount alone says little about positioning. Elevated VIX tells you to expect wider swings, which affects stop size and sizing more than direction.

Write the statement at 9:15 AM ET

Before the 9:30 AM ET regular-session open (confirm the schedule on holidays), write one short statement in your journal. Examples:

Bullish lean: ES is above its weekly open and prior day high, overnight made higher lows, VIX is quiet, no major release before 10:00. I will prioritize longs on pullbacks and take shorts only if the 15-minute structure breaks.

Bearish lean: ES traded below the prior day low overnight and sits under the weekly open. I will prioritize shorts on rallies and skip longs unless the gap fills.

No lean: ES is in the middle of yesterday's range, overnight was sideways, correlated markets are mixed. I will take clear setups in either direction, reduce size, and expect rotation.

Where the KPL map fits

KPL are fixed reference prices anchored to the regular-session opening print, with four levels in the standard ES and NQ map drawn from full-session and after-hours travel. The anchor is not known until the open prints, so you cannot complete the anchored map before 9:30 AM ET, and the levels do not move once set. Treat the pre-market statement as the part you can do now, and add the KPL map after the open as a second layer. The KPL strategy page covers the details. The map is separate from any model context, and it is not a prediction of price.

How the bias guides trading

With a bullish lean, you look for long setups and skip shorts unless the 15-minute structure has clearly turned. With a bearish lean, the reverse. Treat the lean as a filter on frequency, not on size: bias does not mean you should add risk. If a long stalls at a level you identified, take your planned exit instead of hoping for a break. Counter-trend trades are allowed only when the rules you wrote down permit them.

The reset rule

Set the trigger before you start: after two failed trades in the lean's direction, go flat. Then review the 15-minute chart. If price has broken a level that your statement said would invalidate the idea, switch to neutral or flip the lean. If nothing has broken, you may continue at reduced size, or stop for the day if you want to be more conservative. Writing this rule beforehand matters, because you will not judge it fairly when you are frustrated.

Keeping a bullish lean through clear contrary evidence is not discipline, it is confirmation bias. The statement is a tool, and you are allowed to change it when your own written conditions say so.
