Yes, you are correct that P123 is using “Previous Close” price for “Next Open” transaction.
The bug makes “Next Open” simulations useless. Hope the problem is not widespread.
It’s falling back to previous close on the final week of the backtest (affecting daily rebalance), so it’s not a widespread issue. I’ll see what I can do. Thanks for investigating it.
I have settings: Price for Transactions = Average of Next High, Low, and 2X Close
Stock: RNK:POL was purchased today (05/27/24), transaction price = 4.95
The transaction price is from close on Friday.
This stock was not highly ranked to be available to buy on Friday. The rank changed on Saturday. So in real life I would not be able to buy it on Friday.
