Hello! I am impressed with the zorro software, i discovered it 2 weeks ago, and i am trying to get used to it, and test before buying, but today i am very disapointed.

I open the inbluid BuyHold.c strategy, test, and get results, but Annual growth rate is wrong, it tells 26.76%, but it is not, it is more like 15% CAGR (from 117 to 637 in 12 years)

Test period 2013-01-03..2025-07-28 (3159 bars)

I download the data from mi IB account (SPY.t6), and seem fine, in the chart i can see prices are rigth, first price 117, last price 637

I attatch some secreens, but you can try by yourself.....

What i'am doing wrong??
Thanks in advance

Ernesto, "Estotrader"


Edit: I add the files Buyhold.c and Spy.t6 just in case here https://drive.google.com/drive/folders/1yfn-09VhaRwxIvs8MOmpCImuC7qdHDeB?usp=drive_link
