Every broker sets a minimum lot, a maximum lot and a lot step per instrument. A fixed lot below the minimum is refused by PipSync before any order is sent.
Check before a signal arrives
Open Channels → your channel → Settings tab → Auto-trade panel and choose Fixed Lots. Under the lot field, PipSync checks your lot against each linked broker account for the instruments the channel sent in the last 30 days, for example: "0.8 lots is too small for Volatility 50 Index on Deriv Demo (minimum 4)". Click Check again after a change.
Raise to the broker minimum (opt-in)
With Raise to the broker minimum on, a fixed lot below an instrument's minimum is traded at that minimum instead of being refused. It is off by default and:
- applies only to Fixed Lots, never to risk-based or fixed-percent sizing;
- never trades more than your Max Lots or the broker's maximum: in that case the signal is still refused.
A lot that does not fit the lot step is rounded down to the step.
