GBExcellent site for backtesting equity trading strategies Excellent site for testing stock and ETF trading strategies. P123 provides a thorough point-in-time database with a powerful and flexible engine to simulate backtests of systems. And they integrate with Interactive Brokers to automate applying those strategies to live trading.

AUToxic environment Toxic environment that stigmatizes creative, productive, diverse critiques as so-called "unconstructive" and "repetitive" and condones toxic personal attacks.

GBLove the screening with backtests Love the screening with backtests. Forum members are very helpful. Would like access to more foreign markets, log charts, and ability to trade with entry and exits at the $100/mo level.
