Perpetual Futures are a special type of Futures contract that have no expiration date and have an autorolling feature every fourhours.
Below is a detailed table of characteristics, followed by multiple examples to demonstrate the mechanics of the contract:

AutoRoll Period 
Every 4Hours on 12 UTC, 16 UTC, 20 UTC, 24 UTC, 4 UTC, 8 UTC 

Ratesetting Calculation Window 
Rate for next period is calculated over current 4hour period (e.g., rate for 1216 UTC period is calculated in window between 812 UTC) 

Funding Rate 
Between start and end of Ratesetting Period the Funding Rate is computed as the timeweighted average premium, and standardised to a perhour basis. Permissible range per 1 hours: [0.05%, +0.05%] (i.e., 40 basis point magnitude for 8hour realisation period) 

Payout Frequency 
Continuously based on Funding Rate set at the end of the prior Funding Period. Positions will immediately and continuously receive or send funding while open in the perpetual contracts. The funding accumulates as UPL and settles every four hours at end of Funding Period, or when user changes net open position (whichever occurs first). 

Funding Rate Multiplier 
n = 8 This is the coefficient used in the calculation of the funding rate. A value of 1/n means that, ceteris paribus, it will take n hours to realise the Average Premium. Example: if the Average Premium is 0.32% for the four hour period, then Funding Rate is equal to 0.04%, meaning that over the course of 8 hours, this 0.32% total will be realised. 

Funding Rate Calculation 
In a given 4hour Funding Period, Premium values calculated from minutely perpetual contract prices (240 observations) using an Impact Mid are recorded versus the Real Time Platform Ticker. The Impact Mid is the median of the average entry price marketselling 1000 contracts and marketbuying 1000 contracts. The Average Premium is calculated as the average of the mid 120 values recorded from the above 240 observations. Finally, this value is weighted by the Funding Rate Multiplier. If AveragePremium > 0 then for the 4 hour period, those in Long positions will continuously pay out to Short positions, which pushes the price closer to Index. If AveragePremium < 0 then for the 4 hour period, those in Short positions will continuously pay out to Long positions, which pushes the price closer to Index.

Fee Structure 
Crypto Facilities uses a makertaker fee structure. Fees are calculated as a percentage of the notional order value for a matched trade. No fees are charged on autoroll or funding payouts  these occur strictly between counterparties. 

Contract Expiration 
The perpetual futures are nonexpiring, which means that positions in the contract are never “expired” or “matured”, however there is a settlement process every four hours that applies funding to anchor the spot value to the Index. See Last Trading for more information. 

Settlement time 
Every 4 Hours on 12 UTC, 16 UTC, 20 UTC, 24 UTC, 4 UTC, 8 UTC: the accumulated unrealised funding is settled and new rate set based on TWAP premium to index in prior rate period. 

Last Trading 
This contract remains trading perpetually and would only expire in an emergency situation if Crypto Facilities deems necessary to settle/expire the contract. This would only occur in exigent circumstances if the Market Risk Committee deemed it necessary to facilitate a fair and orderly market.

Mid Price of Order Book bounded by a range defined by CF EtherEuro Spot Rate with antimanipulation coefficient 
The Mark Price is calculated using the Premium that is bound to Mid Price, which is capped at a premium of 0.5% for Perpetual contracts. Note: in the extremely rare circumstance that the Index Price is unavailable for whatever reason, the above caps may not apply and the Mark Price will be equal to the Mid Price.

Note on Funding Rate
The funding rate for a given perpetual contract is represented in two different ways:
 absolute rate: The amount of funding an account will receive by maintaining a 1 unit (1 ETH, 1 XBT) short position for 1 hour. This is more useful for account log purposes.
 relative rate: The absolute funding rate relative to the spot price at the time of funding rate calculation. This is an intermediate value in the calculation of the absolute funding rate, and is the number we display in the front end (as a %) as the 'funding rate'.
Examples
In order to get a complete understanding the rate dynamics of the Perpetual Contract, we present examples to demonstrate the key features:
Example Funding Rate 1: (8hour rate realisation length)
Assume time is 12 UTC and that price of BTC is 7,000€ (via BitcoinEuro spot rate) and the Perpetual trades at 7,010€ the whole time until 16 UTC. The average premium is computed as 0.1428% for the 4hour period (10/7,000). This leads to a funding rate of 0.1428 / 8 = 0.01785% per hour.
Now assume that you are in a short position of 10 XBT. If you hold this position from 16 to 24 UTC, and the premium in 1620 UTC period remains as 0.1428%, then you will earn interest of 99.96 EUR for the eighthour period [(10*0.001428)*7000]
Example Funding Rate 2: (Maximum rate)
Assume time is 12 UTC and that price of BTC is 7,000€ and the Perpetual trades at 7,100€ until 16 UTC. The average premium is computed as 1.428% for the 4hour period. This leads to a funding rate of 1.428 / 8 = 0.1785% per hour.
The maximum funding rate per hour in any given period is 0.05%. The minimum is 0.05%.
As a result. this 0.1785% hourly rate is floored to 0.05% per hour, so that the maximum 8hour realisation will not exceed 0.40%.
Note that there is no "dampening" of rates done in this model: if a fourhour computed rate is near 0, then it will stay pay out non0 value even if it is de minimis.
Example Funding Rate 3: (Absolute vs. relative rate)
Assume time is 12 UTC and that the index spot price of XBTEUR is 7,000€, and the relative rate set for the fourhour period is 0.05% per hour.
Now assume the time is 14 UTC and the Perpetual trades at 8,000€ and you enter a Short position of 40 XBT at this price.
You will immediately begin receiving funding at an absolute rate of 0.05%/7,000€ = 0.00000007142€ per hour per unit.
In your available balance you will then see this rate applying in your unrealised PnL through continuous funding payout equal to:
 0.00000007142 * 40 XBT = 139.98€ per hour
 2.33€ per second
This will pay out continuously until 16 UTC where the relative funding rate will change based on the market activity between 1216 UTC.
Assume this new relative funding rate is now 0.03% and the realtime spot index is 7,900€ for XBTEUR at 16 UTC.
In your 40 XBT short position at the end of the 2 hour period you will have 279.96€ applied in your account log at 16 UTC.
From 16 UTC to 20 UTC a new absolute funding rate will begin applying of 0.03%/7,900€=0.00000003797€ per hour per unit.
Example Funding Rate 4: (Variable interperiod rate)
Assume time is 14 UTC and you enter a position long 20 XBT on XBTEUR at 7,000. Assume that the funding rate for the fourhour period (1216 UTC) is set as 0.04% per hour.
At 16 UTC, after you have held this position for two full hours, you will have earned 56 per hour [(0.0004*20 XBT)*7,000]. This is 56*2= 112€, which credits continuously throughout the two hour period you hold it.
However, during this period , the price was at a premium and so the new fourhour rate set for 16  20 UTC is 0.04% per hour. After two hours of holding the position, you have paid 112€ and you close at 18 UTC, two hours later.
Your funding for the four hour period you held the position is thus 112€ for the last two hours of the first period then 112€ for the first two hours of the second period and your net flows are 0 for this.
Example Funding Rate 5: (Fixed intraperiod rate)
Assume time is 14 UTC and you enter a position long 70 XBT on XBTEUR with spot index at 7,000€. Assume that the funding rate for the fourhour period (1216 UTC) is set as 0.033% per hour.
At 16 UTC, after you have held this position for two full hours, you will have paid 161.7 per hour [(70*0.00033)*7,000]. For two hours this costs 161.7*2=323.4€, which debits from your position continuously throughout the two hour period you hold it, in the form of Unrealised Profit/Loss (UPL).
Example Funding Rate 6: (Booking of unrealised funding)
Assume it's 12 UTC you are in a 35 XBT long position on XBTEUR with spot index at 7,000€ and the rate in the funding period is 0.05%. This earns you funding of:
 0.0005 * 35 = 0.0175 XBT
 0.0175*7,000 = 122.5€ per hour
 2.04166667€ per minute
 0.03402778€ per second
 0.00003403€ per millisecond
This credits and debits every millisecond to every user with an open position. It credits first as "UPL" which is "unrealised" profit and loss, but you have the funds available right away to use in further positions or transfer into your Cash account.
The funding accumulates as UPL and is booked into your account log and realised when one of the following events occur:
 You adjust your open position up or down by any amount
 You hold until the end of the Funding Period, at which point it is booked (occurs every four hours)
