They are based on settlement price. This is a bit different than last trade price sometimes it is the same sometimes it is differnt. Hedge funds, floor traders and professional traders us settlement price. See historical deviations page to learn more about settlement.
Implied volatility is gather from 4 options for up to 3 months of contract for a total of 12 IV’s making a IV index for each market.
It is then factoried into a short term 1 day to 5 day deviation formula. The levels posted are currently 1 day deviations.
“isn’t the highest probability of settlement in our favor (lowest risk, best reward) is when the underlying price is at/or near the close price used for the deviation calculations, and we use the +/- .5 deviation strikes for our binaries?” - all depends on what strategy you are doing
note a deviation is probability of touching not probability of expiring so it may move to a deviation level and then go back up/down to the previous days settlement
Since the underlying’s price oscillates during the day, we may not be able to buy right at that price which provides the best risk profile for us. Or, we don’t want to sit at the computer all day to wait for it to come back to the close price. depends on strategy - how do you defined the right price and best risk profile?
But, we can approximate what the price would be of the +/- .5 deviations when the underlying is at the close price using the NADEX price ladder. It seems that the .5 deviations are about 2 strike prices away from the close, and the .7 is about 3 strike prices away. You can estimate price absent of time…as time passes price will change. Deviation levels can fluctuate depending on the IV in the market for that day. The strikes are always the same width apart so .5 2 strikes away may work today but not tomorrow.
I don’t think the .7 dev level would be realistic as it is sometimes too far away and may never be filled. The .5 dev level is more realistic, and should contain 68% of the expected price movement. .7 not realist for what…may not be filled at what price…meanng entry or exit?
+1 or -1 are for a 68% of realistic expected movement in a day - so +.5-.5 are half that 34% of all expected move in a day - meaning there is a 76% chance it will touch/go beyond these levels sometime between the market close of yesterday and the market close of today (including overnight)
Couldn’t you place orders for the +/- .5 dev levels at the market open (or before) using the expected price for that strike price by moving up or down 2 strikes prices on the NADEX ladder? you could place order for the +5 and -5 deviation levels at the market price at anytime after the binaries start trading until a few minutes before the close - 2 strikes is not a consistent thing as discussed above as the deviations vary but the strikes are consistently the same width - i.e. US 500 is always 3 strikes apart - sometimes 1 deviation if 15 pts on es other times it could be only 8 points - so a 2 strike count would not tell you a deviation
All of the above depends on what strategy you are using - buy/sell or straddle etc… what system rules for entry and exit - and style (deviation levels, volume apex pattern etc…) to read the market
Can you expound further on these 3 area regarding how you want to use them and i can give a more direct response…
[quote=dca78_00]Darrell - the deviation levels that you provide are based off the closing price and implied volatility, more or less, right?
So, if that is the case and the probability of these results is a bell shaped curve, then the middle of the curve is the close price (settlement price).
Following that, then isn’t the highest probability of settlement in our favor (lowest risk, best reward) is when the underlying price is at/or near the close price used for the deviation calculations, and we use the +/- .5 deviation strikes for our binaries?
