# Fixed Lot size

This setting allows you to manually define the lot size for every trade the EA places.

* **Set to 0:** Enables automatic lot sizing, where the EA dynamically adjusts trade volume based on:
  * Your **account equity**
  * Selected **risk level**
  * **Lot Size Multiplier**
  * **Trading style**
* **Set to a specific value (e.g., 0.10):** The EA will use this exact lot size for every trade, ignoring changes in balance, equity, or market conditions.

#### ✅ **Why Use It?**

{% hint style="success" %}

#### **When to Use Fixed Lot Size**

* You want **full control** over position sizing
* You're conducting **safe testing** with a small, known volume
* You have a very specific money management strategy
  {% endhint %}

{% hint style="warning" %}

####  **Things to Consider**

When enabled, this setting overrides **dynamic lot sizing**.

Using a fixed lot size removes all dynamic risk adjustments. This means:

* The EA will not scale your trade size according to your account growth or volatility.
* You're fully responsible for ensuring the lot size is appropriate for your balance.
* On smaller accounts, even a moderately sized fixed lot can result in large drawdowns.

When using **Auto Mode (0)**, you still have flexibility and control via:

* [**Risk Level**](/smartchoise-manual/options/risk-management/risk-level.md) (Low, Medium, High, Extreme)
* [Auto **Lot Size Multiplier**](/smartchoise-manual/options/custom-lot-size-settings/auto-lot-size-multiplier.md) (for fine-tuning auto volume)
  {% endhint %}

{% hint style="danger" %}

####  Risks of Using Fixed Lot Size

By choosing a fixed lot size you instruct the Expert Advisor (EA) to execute all trades with the same volume, regardless of market conditions or account changes. This approach disables several of the EA’s dynamic features, including:

* Adjusting lot size based on your risk tolerance and trading style
* Responding to market volatility and conditions
* Scaling positions relative to your account balance and equity

By overriding the EA’s intelligent risk management system, you increase exposure risk, as the EA cannot adapt to fluctuations in the market or your account. 

This makes your trading more rigid and increases exposure to risk, especially during periods of high volatility.

**Recommendation:** Unless you have a specific reason to fix the lot size, we recommend using **Auto Mode** (set to 0). This ensures the EA can scale position sizes intelligently, maintain consistent risk exposure, and better protect your capital under varying market conditions.

🧠 *Use fixed lots for simplicity. Use auto lot sizing for smarter, balance-based scaling.*
