In FYERS Trader, Quick Trade lets you control trade size in two ways: you can adjust the quantity per trade directly on the trading surface, or you can set a persistent Position Sizing method (Amount, Lots, or % Margin) in settings. This article explains both approaches, how they interact with Intraday/Overnight product types, and what to expect in common scenarios.
Scope: This article covers FYERS Trader. For the Overnight product type, only Position Sizing is available (SL/Target not supported).
What you can control
- Per-trade quantity: Change the Units/Quantity before placing an order. This affects only the current trade and does not alter your saved Quick Trade settings.
- Position Sizing rules (persistent): Choose Amount, Lots, or % Margin in Quick Trade settings to auto-calculate quantity for future orders.
Option 1 — Modify quantity for a single trade (Quick Trade surface)
- Open DOM (Depth of Market) or use the chart/Buy–Sell panel in FYERS Trader.
- Edit the Units/Quantity field and place the order.
- Trade-specific change: The modification applies only to this order; your global Quick Trade settings remain unchanged.
- Default for exit: The chosen quantity carries over as the default when you close this specific position.

Tip: Per-trade quantity adjustments add flexibility, but always verify available margin before increasing size.
Option 2 — Set Position Sizing rules (persistent)
- Go to User Settings > Quick Trade in FYERS Trader.
- Select Product Type: - Intraday — Supports Stop Loss (SL), Target, and Position Sizing.
- Overnight — Supports Position Sizing only. Why?
 
- Choose Position Sizing: - Amount — Allocate a fixed capital per trade.
- Lots — Enter a fixed quantity (equity or F&O).
- % Margin — Use a percentage of available margin.
 
- (Intraday only) Map exits if needed: - No SL/Target → normal Intraday order
- SL only → Cover Order (CO)
- SL + Target → Bracket Order (BO)
 
- Enable Quick Trade: Switch the toolbar toggle ON before placing one-click orders.
What if…
| Scenario | Outcome | 
|---|
| I modify quantity in DOM for a single trade | Change applies only to that trade; global Quick Trade settings are unaffected. The chosen size becomes the default when closing that specific position. | 
| I forget to adjust quantity | Order executes with the default size saved in Quick Trade settings. | 
| I increase quantity beyond available margin | Order may be rejected due to insufficient funds. | 
| I leave both SL and Target blank (Intraday) | A normal Intraday order is placed without automatic exits. See details. | 
| I configure SL/Target, but don’t enable Quick Trade | Settings are saved, but one-click orders won’t execute until the Quick Trade toggle is ON. | 
| I try to use SL/Target for Overnight trades | Not supported; only Position Sizing is available for Overnight. | 
Troubleshooting
- Sizing not applied: Ensure your chosen Position Sizing method (Amount/Lots/% Margin) is selected and saved in User Settings > Quick Trade.
- Orders placed without SL/Target (Intraday): Recheck that SL/Target values are configured and saved.
- No one-click placement: Turn the Quick Trade toolbar toggle ON.
