Your portion sets the size
The portion sets the lot size. A larger portion gives larger gains and larger dips, and lets more orders through on the same deposit: 955 trades at 0.65%, 1,043 at 1%. The default is 0.65%.

Buy chai, sell biscuit, on your chart
Each open order gets a see-through zone in its own colour and a caption, so you can tell at a glance what the kitchen is serving.
Chai & BiscuitKitchen panel
The kitchen state, the orders open now, open, daily and total profit, and your portion, always in the corner of the chart.
Sized for your account
Lot size comes from your portion and the stop distance, then is checked against margin, volume steps and broker limits before every order.
Example chart drawn for this page, in the bot's own chart colours. Zones and captions appear only while an order is open.
Everything else is built in
The recipe is part of the bot. You set how much each order risks; the rest is fixed and tested.
- Stop loss and take profit on every order
- Orders below the minimum lot are skipped, never rounded up
- No grid, no martingale, no averaging
- Margin and volume checks before every order
Two settings, that is all
Plus panel, chart colours and magic number. Attach to one gold chart; any chart timeframe works.
