Why is my liquidity position not evenly split between the two tokens?#
It may not be possible to add liquidity to a pool evenly. This is due to the tick spacing of a pool, which is relative to the pool's fee tier.
To add liquidity with a 50/50 value split, a provider needs two ticks that are spaced evenly on both sides of the current price.
For example, if the current price is 3,718.19, then an even +/- 1% range would need prices at 3,681.0081 and 3,755.3719. Adding liquidity at these exact ticks results in an equally distributed position.
However, due to a pool's tick spacing, these exact ticks may not be available. In that case the nearest ticks might be 3,677.5136 and 3,751.8006, which produces a slightly uneven split.
