Probably the most delicate areas in any MT5 commerce copier is lot administration — how the slave determines commerce quantity in proportion to the grasp.
In my newest copier construct, I carried out a number of adjustable parameters to offer merchants full management over danger and place sizing.
Right here’s a fast abstract of how the system handles lot scaling:
-
Steadiness Ratio Management
When UseBalanceRatio = true, the copier robotically compares the balances of grasp and slave accounts.
This ensures that if a slave has half the steadiness of the grasp, it should open trades at half the quantity — protecting danger proportional. -
Lot Multiplier (LotMultiplier)
A versatile approach to scale trades.
As an example, with a multiplier of 0.6 , a 1.00-lot commerce on the grasp turns into a 0.60-lot commerce on the slave.
This easy management is commonly sufficient for many mirror setups. -
Fastened Lot Possibility (FixedLotSize)
For many who choose full consistency, you possibly can disable computerized scaling and use a static lot measurement.
When set to a non-zero worth, all copied trades use that lot, no matter grasp steadiness or multiplier. -
Most Lot Restrict (MaxLotSize)
To stop unintended over-sizing, a security restrict is utilized in order that no commerce exceeds the desired most quantity. -
Free Margin Safety
If FreeMarginPercent is outlined, the copier checks out there margin earlier than inserting any commerce — guaranteeing that solely trades inside protected margin limits are copied.
This mixture of controls offers customers each flexibility and security, whether or not they run similar accounts or mirror trades to smaller danger accounts.
I’ve discovered that balance-based scaling mixed with an inexpensive multiplier gives essentially the most steady efficiency over time.
In the event you’ve examined various strategies for balancing danger between accounts, I’d be glad to listen to about your experiences.
