price change percentage over time

[eliasayyy]

hello everone i have 2 tables 

items table 

price change table

i need to add the price change to the price of my original 

example from jan 1, 2021 the price of I-1 was 75$, on jan 5 ,2021 , it was subjected to a 2.5% increase

so the new price on and after jan 5 2021 should be 75 + (75* 0.025) = 76.8$ 

more over , i have multiple items that has multiple changes over time , i need them to accumulate 

so on jan 5 2021 I-1 was subjected to the 2.5% increase of price but later on on march 30 2022 , it was subjected to another increase of 1% so in total it should accumulate to 75 + ( 75*0.035) 

here is data model for items and dates

i tried this measure but it fails

Have you checked the decimals? Because for 5 Jan, it may be rounding up

its not about the rounding its about how to accumulate the price changes over time based on the item id my formula is incorrect
