Problem description

"smac" strategy's optimization tool is not working.

Example

import fastquant
df = fastquant.get_stock_data("TSLA", "2018-01-01", "2024-01-01")
opt = fastquant.backtest("smac", df, fast_period=range(2,20), slow_period=range(2,30))

Expected behavior

ValueError Traceback (most recent call last)

----> 1 opt = ft.backtest("smac", df, fast_period=range(2,20), slow_period=range(2,30))
