Let's do some math.
Notional value of 2 long ES contracts = 2 * 50 * 2455 = +$245,500
Notional value of 5 short NQ contracts = -(5 * 20 * 5829) = -$582,900
That's not even remotely "balanced". What it is, assuming a perfect correlation between ES and NQ, is a net short NQ position with the notional value of $337,400.
I'm not even sure if this is the correct way to calculate it. I watch NQ and ES very closely, and what I like about them is that for the most part, they move in lock step together. Today of course is a perfect example of when they don't because 2 mins after the open, ES put it in the low of day, and NQ didn't until 37 minutes after the open.
But I think if we wanted to talk balanced, we have to look at the daily range. It is true that when 2 ES contracts move 1 point each, this equals $100, and when 5 NQ contracts move 1 point each, this is also $100. But we have to consider the average daily range.
If I consider a 30 day average, just during RTH, I've got a figure of 66 points for NQ, and 14 points for ES. If I bump this up to 100 days, the ES is still at around 14, and NQ drops to 45. But still, looking at the graph, there is a high-low of 45-32 for NQ and ES is 16-13, so taking a guess at what the range for the day will be is difficult.
Suppose we were able to catch the exact high and low during RTH. Using just the 30 day average, this means 5 NQ contracts for 66 points is $6,600 (profit or loss), whereas for ES, 2 ES contracts for 14 points is $1,400. This is quite a bit different isn't it. So if we're going to be long 2 of ES, and short 5 of NQ, the NQ bias is very very heavy.
Using the above numbers for the value of each contract from
@nonlinear5 , the ratio of ES to NQ is 0.42, but using the money gained or lost with my moving average daily RTH range, the ratio is 1400/6600 = 0.21.
Its of course impossible to know which days the NQ will have a huge range, and which the ES will, but to be somewhat neutral, it seems like the amount of ES contracts that are needed are at the very least double since the NQ tends to have very wide ranges.
Worst of all, like today, you could have gotten long NQ and short ES, assuming you're somehow "hedged", and both would end up being losers until later in the day since there was that initial divergence. Eventually they did start to move together, but patience and timing is critical.
