When Composer may still suit you

Composer suits long-term US stock and ETF investors who want rules-based portfolio rebalancing.

Backtests you can trust

AlgoBars backtests use only the data available at each moment and fill orders on the next bar, so a result reflects your rules, not hindsight. They show the raw price move, before spread and commission, so you see the edge of the rules themselves. Check each broker's spread with the broker spread map before going live.
