App version 4.1.4 is live!
This update replaces “price difference” in the pDEX pro dashboard with “size impact”. Size impact shows the difference between the current price of an asset and your estimated trade quote, based on the current and resulting liquidity pool ratios. This makes it easy to know whether you’re getting a good rate, and how far it deviates from the asset price.
What’s the difference?
Price difference showed the difference between pDEX prices and external market prices, after accounting for the default slippage rate.
Size impact, on the other hand, is a more standard feature in DEXes. It shows the variance of prices in the same DEX you’re using, by accounting for the size of your trade in contrast with the amount of available liquidity.
Based on feedback from users, many people assumed that’s what the pDEX was showing with price difference, so we’ve changed it to meet your expectations.
What’s new?
The pDEX now shows size impact on both the simple and pro dashboards, calculated as a percentage with the following equation:
(Trade output amount) / (liquidity pool size) x 100 = (impact %)
This means that size impact is determined by the size of your trade in relation to the balance of liquidity available. Larger trades, then, have larger size impacts.
The ratio is multiplied by 100 to format it as a percentage. The minimum impact is 0.01%.
Note: This field does not show when you trade with pUniswap or pKyber.
Additionally, there is now a refresh button that you can use to reload the quoted amount if you wait too long before making a trade.
