Minimum trading unit and leverage
Minimum trading unit and leverage are product-level trading parameters.
In Finger Manager, institutions can configure the Minimum Trading Unit and Leverage for each Trading Desk or ticker independently.
These parameters participate in order validation and trading-rule checks. After the configuration is saved, the system processes customer order requests according to the latest rules and can synchronize the parameters to the Finger Trader product trading page.

01 What the minimum trading unit means
The minimum trading unit defines the smallest quantity a customer can use when submitting an order for a product.
For example, if NZD/USD has a minimum trading unit of 0.10 lot, customer orders for this product cannot be lower than 0.10 lot.
If the customer enters a quantity below the minimum, the system can reject the request or ask the customer to modify the quantity according to the current order rules. The minimum trading unit answers the question: how little can this product be traded?
02 Different products can use different minimum units
The minimum trading unit is product-level configuration and does not require every product in a market to use the same rule.
For example, NZD/USD may use 0.10 lot, XAU/USD may use 0.01 lot, AAPL may use 1 share, and BTC/USDT may use 0.001 BTC.
The exact unit depends on product type, trading system, and institution business rules. Finger Manager can maintain different parameters for different markets and tickers.
03 Trading units and product types
Different asset classes usually use different quantity units.
Forex commonly uses lot, mini lot, or micro lot. Stocks commonly use share or fractional share. Digital assets can use BTC, ETH, token quantity, or another asset unit.
CFD or OTC products can define contract, lot, or another trading unit according to the institution's product rules. When configuring the minimum trading unit, administrators should also confirm the quantity unit used by the product.
04 What leverage means
Leverage describes the relationship between a product's notional trading value and the capital required under the product rule.
For example, 1:50 means that, if product rules allow it, a customer may control a larger notional position with a smaller margin amount.
Leverage does not directly change product price. It mainly affects margin requirement, notional position size, risk exposure, and some risk calculations.
05 Leverage example
For example, if a product is configured with leverage 1:50 and the customer opens a notional position of 50,000, the theoretical base margin ratio is about 1 / 50, or about 2%.
Actual margin requirement can still be affected by product rules, account type, risk parameters, broker or execution system, market volatility, and institution internal margin rules.
Therefore, the leverage shown in Finger Manager should remain consistent with the institution's actual trading and margin system.
06 Different products can use different leverage
Leverage is also a product-level configuration.
For example, EUR/USD may use 1:50, XAU/USD may use 1:20, BTC/USDT may use 1:5, and AAPL CFD may use 1:10.
Institutions can configure different leverage ratios according to asset class, market risk, and internal business rules. It is not recommended to apply the same leverage ratio to every product.
07 Minimum unit and order validation
When a customer submits an order in Finger Trader, the system checks whether the quantity follows the current product configuration.
For example, if the minimum trading unit is 0.10 lot and the customer enters 0.05 lot, the system can identify the quantity as below the permitted range and stop the order from continuing.
If the customer enters 0.10 lot or a higher valid quantity, the request continues to the next order-validation step. The minimum trading unit in Manager directly participates in live order-rule checks.
08 Leverage and account risk
Higher leverage usually means a customer can establish a larger notional position, while the account may also become more sensitive to price movement.
When configuring leverage, institutions should consider product volatility, margin rules, customer type, account type, risk tolerance, local regulatory requirements, and the actual limits of brokers or liquidity providers.
Finger Manager provides parameter configuration. It does not decide on behalf of the institution what leverage a product or customer should use.
09 Front-end display
After product configuration is completed, Finger Trader can display the corresponding trading parameters according to the institution settings.
For example, NZD/USD can show Minimum Trade Size 0.10 lot and Leverage 1:50.
Whether all parameters are shown directly in the client depends on Finger Trader product-page design and institution configuration.
10 How saved changes take effect
After an administrator modifies minimum trading unit or leverage, the new product parameters must be saved.
Once saved, the system processes subsequent trading requests according to the latest configuration.
The flow is: Manager modifies parameters, saves product configuration, updates trading rules, Finger Trader obtains the latest parameters, and subsequent customer orders are validated against the new rules. Historical orders are not retroactively changed by parameter updates.
11 Checks before changing parameters
For products already live and traded by customers, changes to minimum trading unit or leverage should be handled carefully.
Before changing parameters, administrators should confirm whether there are current positions or unfinished orders, whether the new parameters match broker or LP rules, whether the OMS supports the new quantity rule, whether margin calculation has been synchronized, whether current customers will be affected, and whether customer notification is needed.
Leverage changes can directly affect margin requirement and available-funds calculation, so they require particular care.
12 Difference from quantity step
Minimum trading unit and quantity step are not the same concept.
Minimum trading unit means the smallest order quantity, such as 0.10 lot. Quantity step means how much the order quantity can increase each time.
For example, if the minimum trading unit is 0.10 lot and the quantity step is 0.10 lot, customers can submit 0.10, 0.20, 0.30, or 0.40. If the product supports independent quantity-step configuration, it should be configured separately according to real trading rules.
13 Difference from price precision
Minimum trading unit controls order quantity. Price precision controls decimal places for order prices and quote prices.
For example, a product can use price precision 0.00001 and minimum trading unit 0.10 lot.
These are different product parameters and should be configured independently.
14 Regulatory and institution rules
Different jurisdictions may impose different restrictions on leverage, margin, and product trading units.
Before configuring product parameters, the institution should confirm the scope permitted by its license, local leverage restrictions, customer-type limits, product suitability requirements, broker or LP trading conditions, and its own risk policy.
Finger Manager provides technical configuration and rule-execution capability. It does not represent regulatory approval of any leverage ratio or trading unit.
Minimum trading unit and leverage can be understood simply: minimum trading unit means the smallest quantity a customer can order; leverage means how much notional position can be controlled with a given margin amount.
For example, NZD/USD with minimum trading unit 0.10 lot and leverage 1:50 will use those latest product rules for subsequent order validation after Finger Manager saves the configuration.
For products already traded live, especially leverage parameters, frequent changes are not recommended without completing business and risk confirmation.
