Open Drive and Opening Range

Cash open vs globex open — two different auctions.

Intermediate 6 min read Course 26 of 60

Course 26 of 60 in the futures hub. Equity index futures trade before the stock market opens, and they trade again when it does. This lesson separates those two auctions and prices an opening-range stop on the E-mini and the micro.

Two opens, two auctions

There are two opens, and if you fold them into one box, the rectangle on your chart is lying to you. The Globex reopen, Sunday evening included, often prints on a thin book. The cash open, around 9:30 am Eastern, is when stock-index liquidity shows up. A playbook written for the second open gets chopped up on the first. A box drawn at 7 am is just ink until you say which auction made it.

The range is a map of the auction you actually chose. Name that auction in the journal before you mark the high and the low. Spot forex has no stock bell, so a currency opening habit doesn't transfer onto ES. Session structure for those pairs lives in the forex course.

1. The Globex open

The Globex open is a real print and a poor place to borrow confidence. A gap at the Sunday reopen is the first trade after a closed stretch. Direction can wait for a thicker book. If you still draw a range on that session, label it Globex and keep it in its own column. The diagram is blunt: the overnight range and the cash range answer different questions.

Thin books punish tight stops. A modest order can walk price through a level that looked firm during the prior afternoon. My default is smaller size, or none, until the cash open, unless the plan was written for the overnight and the stop's dollars still fit the cap.

2. The cash open

The range people mean by opening range starts near 9:30 am Eastern. ES is $50 times the S&P 500 index, and the minimum step is 0.25 index points, worth $12.50 a contract. MES is one tenth of that: $5 times the index, so the same 0.25 point step is $1.25. Any stop you intend to honor has to be converted with those two numbers before the bell.

ES opening stop: 10 ticks times $12.50 = $125. $191 minus $125 leaves $66, so the count is 1 ES. A 25-tick stop is 25 times $12.50 = $312.50, which is more than $191, so the ES count is 0. MES is $1.25 a tick: 25 times $1.25 = $31.25, and 6 times $31.25 = $187.50. $191 minus $187.50 leaves $3.50, so 6 MES.

So when the open needs 25 ticks, your choices are six micros or no trade. Six micros are lighter than one ES: 6 times $5 is $30 times the index, next to $50 for the E-mini, and they are still a live position. Run your own cap and stop through the futures contract size calculator; ES and MES are both on its list. If the open is already wider than the stop the cap can fund, the honest ticket is no ticket.

3. Drive days and balance days

A drive day leaves the opening range and holds outside it. A balance day stays in the box and rotates from one edge to the other. You only know which you had after price either stays out or comes back. Wanting a trend day doesn't produce the hold.

Overnight direction can talk you out of fading a break that has already been accepted outside the range. It shouldn't be the reason you click. If the overnight high sits a couple of ticks beyond the cash range, decide whether that changes the plan before 9:30. Editing the meaning of 'broke' after you see the break is how a balance day gets traded like a drive.

4. A failed opening range

A failed opening range is information you can use or ignore. On a day that never leaves the box, fades live at the edges, and the target has to stay inside the range because there's no trend paying a runner. On a day that leaves and holds, the trade is the drive: trail it, and if price returns inside the range the drive idea is finished.

The trap is the break that leaves and snaps back. Fade it back into the range, or pass. Chasing the break after it has already failed is paying the trader who set the trap. Pick which of those sessions you're allowed to trade, and write it down before the bell. Someone allowed all of them, with no written difference, will find a reason to be in every print.

5. Index opens and commodity opens

This two-open pattern belongs to products that wait on a stock-market bell. Crude, gold, and grains get busy on their own clocks, tied to their own reports. An opening range measured from 9:30 Eastern on a commodity future is a box around an arbitrary minute. The day-trading lesson is where an index window gets chosen. That choice doesn't hand you a window for crude.

If you trade both families, keep two definitions on paper. Index: cash open, a set number of minutes, break or fail. Commodity: the hour that market treats as its main open, in that market's time zone. Use one definition for both and a decent index week ends up paying for a bad crude morning.

6. Where opening-range trades go wrong

Running the cash-open playbook on a future that has already traded all night. Widening the range after the first break fails, so the box always agrees with you. Treating 25 ticks of needed room as a detail when the cap only pays for 10 ticks on ES. Standing in a commodity open with an equity clock.

A scheduled report that lands on the bell can turn the whole box into noise. The scheduled-reports lesson is the calendar for those mornings. Pick how many minutes build your range and leave it alone. If you change it after the break, you never had a number.

The cash open sets the range that usually matters

On equity index futures the evening session and the next morning's stock open are both real prints, and the morning is usually where the size shows up. The first stretch of that cash session is what the rest of the day keeps referring to. Plenty of those ranges are noise: a high and a low that never mattered, with traders getting chopped because they felt obliged to honor the box.

Fill in the blanks before the bell and then leave them alone. How many minutes build the range. What counts as a break that held, as opposed to a wick. What a failed break does to the position, including getting flat. Empty blanks mean you don't have an opening-range trade yet.

Your opening-range checklist

  • Label the box Globex or cash before you trade it. The Sunday gap is a print after a halt.
  • ES is $12.50 a tick, so 10 ticks is $125 and 25 ticks is $312.50. MES is $1.25 a tick.
  • A $191 cap funds 1 ES at a 10-tick stop and 0 ES at 25 ticks. The 25-tick case is 6 MES, with $3.50 left.
  • A drive has to stay outside the range. A wick that comes back is a failed break, and chasing it pays the trap.
  • Don't drop a 9:30 opening range onto crude, gold, or grains.

If the high and the low on your chart were printed at 7 am, call them the overnight range or don't call them a range at all. Educational only. Not a recommendation to buy, sell, or hold any contract or pair.
