Do you know how the amount of token locked in a tick is calculated?

We can see this information in the histogram from Uniswap
https://info.uniswap.org/#/pools/0xd0fc8ba7e267f2bc56044a7715a489d851dc6d78

Thanks for your app which is useful to see how much fees one can earn.

It would be great if the selected tokens can be added to the url so refreshing the page doesn't force you to select the tokens again.

Hi - great tool and thx for sharing!
would it be possible to add L2 support for Optimism and Arbitrum?
I tried to replace the graph URL to OE but apparently token addresses have to be retrieved somehow differently too and my coding skills are not good enough to change myself.
Best,
Nikolai

Reproduces on ETH:ENS pair with 0.3% tier.

To reproduce:

1. Select ETH
2. Select ENS (4 ENS's show up, seems the 2nd option is the correct-est one?)
3. Pick any fee tier (e.g. 0.3%)

Loading throbber throbs forever, console gets an error:

When certain tokens are selected, Tokemak (0x2e9d63788249371f1DFC918a52f8d799F4a38C94) for instance, an error is thrown:

Uncaught (in promise) Error: Unable to find token from contract address "0x2e9d63788249371f1dfc918a52f8d799f4a38c94"

When this occurs the app is broken and a refresh is needed to continue. Also there is no information presented to the user to alert them. I was wondering why the loading image was spinning forever so I decided to take a look at app and noticed this error.

Amazing calculator! I have been looking for a tool like this since v3 was launched. Thank you very much for making this.

My first impression for the liquidity distribution visual was a little confusion as I am used to the chart on uniswap info.

For example:

Vs

Would create more continuity between the two graphs if they were presented similarly.

src/utils/math.ts:115

const amt0 = expandDecimals(amount0, token1Decimal);
const amt1 = expandDecimals(amount1, token0Decimal);

Looks like the decimals are reversed.

Please add Ethereum L2 fee calculation options. Start with Arbitrum.

So far from all the calculators tho this one is by far the most responsive in terms of performance and interactivity. Thanks!

At The liquidity delta calculation the code for amt0 and amt1 have a issue .
the code shows
const amt0 = expandDecimals(amount0, token0Decimal);
const amt1 = expandDecimals(amount1, token1Decimal);
which is wrong as per my understanding
link to code https://github.com/chunrapeepat/uniswap.fish/blob/4102d32eea54b40b75afd09be852166dec934352/src/utils/uniswapv3/math.ts#L248

Add guidelines for some concepts like fee tiers (0.05% or 0.3% vs 1%, fee tiers strategy), price ranges, range order, etc.. so that newcomers know how to plan their strategy

• I think the problem is from the not updated "./src/utils/tokenImageURI.json" file

Good evening, I would like to install this impermanent loss calculator that you have on your website on a self-hosted basis, is there a step-by-step guide on how I do this? I'm from infrastructure, so I know how to set up a vm for this, but I wanted a step-by-step guide or a Python script where I enter the same data: Deposit Amount, Min Price, Max Price, Most Active Price Assumption, and then the option to simulate the same price as the Current Price and Future Price impermanent loss calculator and bring the same data, but instead of via the web, it would be via text.

RIght now on the arbitrum token list there are two USDC which is kind of confusing.

Dragging the mouse to select the price can be tricky to get an exact range. By having a + and - button a user can more easily dial in the price they want to calculate.

Using Chrome on Windows 10

The calculator assumes a linear-return as the number of days progress towards the calculated Future Price. In reality, as that price is reached, the underlying fees generated have increased in value.

Take note here:
1 day position = $0.94 return
200 day position = $187.53 ($0.94 * 200)
In reality, the position would be generating MATIC and USDC, where MATIC is increasing in value. So a linear return isn't the ideal calculation here.

When the position of days is increased, I would expect to see the return of MATIC and USDC increase rather than stay the same - that way it could factor in increase in value.

Simpler way to view this problem

It's easier to visualise if you increase the Future price to be something extreme like $500 in future, across a 200 day position:

Take note of 1 day position, $0.94 yield, $1.5 future price

Take note of 200 day position, ONLY $187.53 yield, yet $500 future price

Clearly this doesn't make any sense. If your earning yield for 200 days generating MATIC and it's future price is $500 per MATIC, the yield wouldn't be only $187.53

Hope that makes sense?

Hi Chun, error loading RWASTE:ETH Pair

Hey Chun,

Great app. Possible to make it so the 2 Min/Max fields are independent of each other?

Kind of frustrating when you're typing in a number in Min Price and have to type in the Max Price again, if you've already set it. Easy to do when trying to calculate multiple positions.

It took me a bit of time to figure out how to analyze wide ranges. I am not familar with the limitations of the visuals/slide bar; but if it would be possible to have the charts work with passive range Liquidity Providing. I would very much appreciate it!

Again great job; this tool should definately get a grant! Best one I have come across.

Do you know any other data source for uniswap fish to work when thegraph is not working?

Are the USDC/ETH estimated fee calculations correct? The estimated fees look very high - when you go to select a min and max price they appear to be reversed to start - didn't know if the estimated collection fees were really this high or if there was a bug in the software for the estimation with min/max price. Thank you!!

hi, seems to be an issue with token selection.
it just gets stuck on loading...

..

I really like your project. just found some minor UI issues and will report them. I hope you don't mind.

In the correlation chart, the marker which indicates the price at the current cursor position is partially covered, which makes it hard to read the actual price when one want to get a rough feeling for it.

same issue with the liquidity position chart.
