Scale In / Scale Out Simulator

Model a full scaling strategy — add multiple buy levels (averaging down or pyramiding up) and multiple sell targets (laddered exits). See your average entry, total ROI and per-lot P&L on a visual ladder diagram.

// Averaging Down

Buying more at lower prices reduces your average entry price, bringing break-even closer. Risky if the stock keeps falling — only average down in strong companies.

// Pyramid Buying

Adding to a winning position (buying at higher prices with smaller sizes) keeps your average entry manageable while increasing exposure to a proven move.

// Laddered Exits

Selling at multiple targets banks guaranteed profit at each level while maintaining partial exposure to further upside. This is the core of the Scale-Out strategy.

// Risk-Adjusted ROI

ROI calculated only on the shares that have been sold. Unrealised positions are shown separately to avoid counting unbanked gains as realised profit.
