Start with a strategy

Describe any trading strategy in plain English. Here's an example:

RSI Mean Reversion

Buy when RSI(14) < 30, sell when RSI(14) > 70. Stop loss 5%.

Our parser understands:

ENTRYRSI(14) < 30

EXITRSI(14) > 70

RISK5% stop loss

This looks like a solid backtest candidate. But is it robust?
