Systems that trade a defined allocation to a defined rule set, with every fill written to your statement.
Each strategy states its entry condition, exit condition and maximum exposure before you allocate to it.
A strategy can only ever trade the amount you allocated. It cannot reach the rest of your balance.
Stopping closes open positions at their current value and returns your allocation plus realised P&L.
Automation removes hesitation, not risk. A strategy that performed well in one market regime can lose steadily in another.
