Options backtesting software for SPY, with an Optimizer, a Simulator and an AI trade box. Backtests fill on one-minute bid/ask quotes with commissions. The Optimizer prices every stop-loss and profit-target combination on the same trades, shows the grid, and checks the pick on trades it never saw. Replay any trade minute by minute and manage it yourself in the Simulator. Describe the trade in plain English and the AI sets it up. Private beta trial: sign-up open, no invite.
