We will be learning python file handling we will see that why we need to have a good understanding of the file handling so we can say we can perform all these modes on unic code files also and binary files also go here and check the file trade CSV you will see that we have something inside it this is and that says this is the best YouTube channel for algo trading but I have still not subscribed it is it true welcome back to the day 15 of the 100 days of hell with python algo trading and why I call these 100 days as hell because in these 100 days I’ll be waking up at 2: a.m. every day straight for 100 days and I’ll be creating content for you guys so today is the day 15 and we have successfully completed 2 weeks before this so today we’ll be learning python file handling and we will see that why we need to have a good understanding of the file handling because in algo trading we’ll be dealing with so many types of files right for example Json CSV Excel and binary files so we need to have a strong grasp on that so that in any scenario we do not mess up with the files and we are safe right okay let’s see this file handling in algo trading is vital for managing data developing strategies and executing trades because whenever we are managing different kinds of data and while we are developing strategies and even when we are executing trades we’ll be dealing with different kinds of files right and for that.

File Handling

We need to have a stronghold on the file handling so let’s see the use case of file handling in algo trading the first is historical data management so inside that we’ll be saving data so downloading and storing historical prices in formats like CSV and Json we will be dealing a lot with the CSV and Json files so it becomes another use case then loading data so reading historical data for analysis back testing and training models right so while like in machine learning models we’ll be using this also then we have the trade loging so recording executions saving trade details like symbol price quantity for record keeping and maintaining logs so logging trading activities errors and alerts for auditing so like 

When we are executing trades so we need to have a robust system where we are keeping our records that at which price at which day which time and at which symbol like everything we need to keep details right we cannot just make trades and just forgot about that and again we also need to maintain logs like if we are getting some error then we need to have a record that which error is coming so that we can debug the issue quickly correct so the next is for the configuration storage so in this we have storing configuration so saving algorithm parameters strategy settings and API keys in Json or yaml files so this is another use case right and also then after storing those configuration.
