get data from a specific trading day in the past

[sharehunter 10]

Hi,

I do a backtest so need some data in the past. Please kindly help me about the formula to get data from a specific trading day in the past (for example: get closing data in 05/30/2010)

Many many thanks

From where and in which format did you get your data? You can use Excel or Python Pandas Dataframe to get price on specific day or range using simple slice methods by row indices.
