A suggested price of 1873.459 must be rounded down to 1873.46 if the tick size is 0.01. This micro-detail is where most cross-broker systems fail. 📉

Here’s what makes robust trading automation work:

1. Symbol Mapping: Ensures your strategy remains functional even when different brokers use different names for the same asset, allowing the automation to correctly resolve the intended instrument symbol for the connected account. 🌐
2. Automatic Handling: The system automatically handles the complexities of tick size and step size—the two critical rules enforced by the broker's API for every tradable symbol.
3. Tick Size: Dictates the smallest permissible increment for a price. Any price sent outside this grid will be rejected or altered by the broker. ⚠️
4. Step Size: Dictates the minimum increment for the quantity you can trade in lots, requiring volume inputs to align with this grid.
5. Order Construction: The automation reads the specific tick size and step size from the broker’s live instrument information and performs necessary rounding when constructing an order.
6. Dynamic Reading: This process is crucial because these values are not constant; hard-coding them makes any automation fragile the moment a broker updates its quoting rules. ⚙️
7. Validation: The system validates the symbol against the broker’s live symbol list before sending an order, ensuring a naming mismatch surfaces as a clear error rather than a failed execution. ✅
