"Stacked data: This may seem fairly trivial but actually streamlines the process for alphas where the data frequency is low enough that this is possible. Normally you would do: SYMBOLS = . tools . data_loader( start_date="2023-01-01" end_date="2025-01-01" data_type="trade_bars" frequency="1h" symbols=SYMBOLS ) and it would behind the scenes look like: dfs = for symbol in symbols: for date in pd . date_range(start end): load in the data append to dfs return pd concat(dfs) This is probably one of the most common tools to use but it's actually quite slow. It takes about XX mins to load in hourly"

"Always ensure your .resample() is: .resample("X" label="right" closed="right") By default it's left so the start of the period is the timestamp (instead of the end of it) Easy way to produce lookahead is by forgetting this. Most LLMs will not add this"
