How we ranked them
TradingView #1 because Pine Script is the most accessible scripting language for backtesting custom strategies.
ThinkOrSwim #2 with thinkScript — more powerful, steeper curve. TradeStation #3 for EasyLanguage. TrendSpider #4 for visual strategy testing. SultraxAI #5 (backtesting is on the roadmap; current value is the live published win rates, which are real-world performance rather than backtest curve-fits).
