How much money should I allocate to each strategy?

Work backward from the drawdown you can genuinely tolerate. Look at the strategy's backtested maximum drawdown, assume the live future will exceed it (it usually does — the backtest's worst case is one sample), and size so that scenario is annoying rather than devastating: if you can stomach losing $1,500 and the strategy's plausible worst case is 40%, the allocation is ~$3,750. Diversify across strategies with different mechanisms — a mean-reverter and a trend-follower fail at different times, so sleeves running both smooth the account curve. And keep allocations honest: adding cash to a winner every week is momentum-chasing your own strategies; rebalance on a schedule instead.
