QUANTCONNECT COMMUNITY
Hi, Colleagues,
This is my first algo on QC, so don't judge strictly.
The idea is to backtest delta neutral trading, gamma scalping, ect. We buys nearest ATM strangle and every minutes do delta hedge with Underlying.
But unfortunately backtest is going very slowly :(
Maybe someone could help me to optimize my code to speed up this algo.
