Time-weighted common value is an algorithmic commerce execution technique generally utilized in conventional finance instruments. The objective of the technique is to provide a mean execution value that’s comparatively near the time-weighted common value (TWAP) for the interval that the person specifies.
TWAP is principally used to cut back a big order’s impression in the marketplace by breaking it down into smaller orders and executing each at common intervals over a time frame.
How TWAP can scale back the worth impression of a big order
Bids can affect the worth of an asset within the order books or liquidity within the liquidity swimming pools. For instance, order books have a number of purchase and promote orders at completely different costs. When a big purchase order is positioned, the worth of an asset rises as a result of the entire most cost-effective purchase orders are being executed.
For instance, Coin A is at present priced at $10 and has the next:
- 50 purchase orders at $10
- 50 purchase orders at $11
- 50 purchase orders at $13
- 100 purchase orders at $15
- 500 purchase orders at $17
Dealer A locations a purchase order of 300 Coin A tokens at a value o $17. Because the order quantity is bigger than the cheaper orders, the protocol will execute the $10, $11, $13 and $15 value factors to satisfy the order.
Nevertheless, for the reason that whole purchase order isn’t sufficient to fill all of the bids at $17, the worth for Coin A will cease at that degree. That’s a value enhance of 70%, principally seen with low liquidity cash. Most often, the worth enhance can be much less dramatic.
Although most decentralized exchanges (DEXs) don’t have order books, they’ve automated market makers (AMMs) that modify the worth of a token based mostly on order dimension and the scale of the liquidity pool. Liquidity is sourced from liquidity suppliers (LPs) who contribute a specific amount of a token pair to the pool in return for a lower of the charges.
As a result of liquidity in decentralized finance (DeFi) is extra scattered than in additional established monetary markets, the issue of a single transaction having an outsized affect in the marketplace could also be extra vital. TWAP methods can doubtlessly resolve the worth impression drawback, for instance, by executing trades in 4-5 minute intervals over an hour.
Breaking apart the bigger order can provide the DEX time to resolve any value variations throughout the respective liquidity swimming pools, serving to to carry the asset again to its spot value. The technique can profit DEXs since bigger value impacts can have an effect on the token pairs within the liquidity pool.
For instance, the cheaper token within the pair can find yourself with much less liquidity, resulting in greater slippage (the distinction between the anticipated value of a commerce and the precise value it executes at). Elevated liquidity can facilitate bigger buying and selling volumes for a DEX and supply a greater expertise for merchants.

Slippage often happens because of low liquidity that can’t attain demand, growing an asset’s value. Ran Hammer, vp of enterprise improvement at Orbs, a decentralized public layer-1 blockchain, shared his ideas on whether or not TWAP may enhance slippage on DEXs.
Hammer advised Cointelegraph, “TWAP, used correctly, can positively enhance slippage and value discrepancies. Each of those issues come up on DEXes when a commerce is simply too giant relative to the general liquidity within the pool and has a disproportionate impact.” He continued to say:
“TWAP methods can mitigate this drawback by creating smaller orders and giving arbitrageurs a brief window to shut any value discrepancies and produce the reserves again to equilibrium.”
Deg3ntrades, a part of the undoxxed improvement staff at SpiritSwap — a decentralized trade and DeFi platform on Fantom — additionally shared his ideas, mentioning decentralized TWAP (dTWAP), the model of TWAP applied on SpiritSwap.
Deg3ntrades advised Cointelegraph, “By design, dTWAP orders fragment trades into batches of smaller trades permitting the person to specify when these trades are executed at common intervals over a pre-defined time frame. This outcomes out there with the ability to soak up and decrease the worth impression of huge orders throughout buying and selling pairs struggling low liquidity.”
“Attributable to latest occasions out there which are out of the management of the DeFi neighborhood, liquidity crunches are a outstanding subject proper now, so Orbs integrating dTWAP with SpiritSwap couldn’t have come at a greater time.”
Primarily based on the feedback above, smaller orders can enhance liquidity by decreasing the variety of tokens exchanged and permitting the liquidity swimming pools to be re-stocked between buying and selling intervals.
How TWAP can automate the dollar-cost common course of
The phrase dollar-cost averaging (DCA) refers to an investing technique by which an investor makes fastened dollar-amount purchases of an asset or portfolio of belongings (i.e., $100 each week). The DCA technique is used when market volatility is excessive or a dealer has a partial quantity they wish to make investments on the time.
For instance, if Coin B’s value fluctuates each different day for a month, an investor can purchase $250 price of Coin B each week as a substitute of attempting to purchase at an ideal time. It’s because the price will ultimately attain a mean value level over time, regardless of the asset’s fluctuating value.
TWAP might be applied by a dealer to mechanically dollar-cost common their orders. The technique works by inserting longer intervals between orders and a bigger total time interval for the trades. For instance, trades might be positioned at bi-weekly, weekly or month-to-month intervals over a number of months, a 12 months or indefinitely.
Decentralized time-weighted common value
Decentralized time-weighted common value is a model of TWAP developed by Orbs for DEXs and AMMs. The protocol permits decentralized buying and selling platforms to unfold out trades over time and has already been applied on the SpiritSwap DEX.
The dTWAP good contract makes use of a “maker” and “taker” system. The maker is the person who locations the order on a DEX, they usually’ll have the ability to configure the restrict value, order intervals and order expiration.
The phrase “taker” refers to an impartial occasion that oversees the orders submitted by customers (makers) on the DEX. The taker goals to seek out one of the simplest ways to execute the batch of orders and bid on those self same orders when discovered. Takers obtain a payment for bidding on orders and compete with different takers who could also be bidding on the identical orders.
Takers set a payment, with the minimal quantity being sufficient to cowl the transaction payment for trades. Validators on the Orbs community, referred to as “Guardians,” perform as takers within the protocol, mechanically calculating and bidding on a number of orders for the maker.
dTWAP person expertise
The decentralized time-weighted common value protocol has a conveyable person interface that may be built-in into DEXs. Trades utilizing the protocol might be break up into market orders (executed at present market costs) or restrict orders (executed at a particular value or higher).
When setting trades to execute on the present market value, the dTWAP good contract will accomplish that on the person’s intervals. Concerning restrict orders, as soon as a person units the restrict value, trades will solely execute if that value is offered on the chosen intervals. The commerce won’t be positioned if the restrict value is unavailable. Attributable to this, an order may solely have a part of its trades executed if the specified restrict costs aren’t reached.
For instance, a person units a restrict value of $50 or much less for Coin C, with seven intervals over 4 weeks (28 trades whole). Throughout week two, the worth didn’t attain $50 for 3 days, so 4 trades had been executed (out of seven for that week). So in whole, 25 of the 28 trades for the order had been executed.
Who advantages
TWAP might be helpful for merchants who wish to purchase into decrease liquidity tokens or automate their buying and selling course of.

“TWAP has two fundamental makes use of that profit merchants. One is the flexibility to make giant trades or trades in pairs which are long-tail and low-liquidity with out disrupting the worth. Second, it may be used to automate dollar-cost averaging methods (the place the dealer purchases an asset or units of belongings on a particular schedule),” Hammer mentioned, persevering with:
“TWAP can be utilized to assemble such methods in a manner that doesn’t require any further motion from the dealer apart from ensuring sufficient funds can be found to finish all trades.”
Deg3ntrades acknowledged, “The flexibility to make the most of TWAP orders not solely reduces merchants’ publicity to excessive slippage/value impression on giant orders or when buying and selling in low liquid pairs but in addition opens up and makes accessible a plethora of latest buying and selling methods to extra well-versed and superior DeFi customers, comparable to automated greenback price averaging.”
Decentralized time-weighted common value methods can enhance the expertise of each merchants and decentralized exchanges. As well as, the elevated liquidity, lower cost impression and commerce automation of dTWAP may additionally enhance engagement between customers and DEXs.
