# Custom Lot Size Settings

You can keep the EA in **Auto** mode (recommended for most users), or override it with **fixed** or **percentage-based** sizing when you need strict, predictable exposure.

{% hint style="info" %}

### How to think about it (3 sizing modes)

#### 1) Auto lot sizing (dynamic)

The EA automatically calculates lot size based on things like **equity, selected risk level, trading style**, and your fine-tuning settings.

Use Auto when you want the EA to **adapt** as your account and market conditions change.

**You can still control Auto with:**

* **Auto lot size multiplier** (makes Auto lots smaller or bigger)
* **Max Auto Lot Size** (hard cap so Auto never exceeds your limit)

***

#### 2) Fixed lot sizing (manual)

You force the EA to use **one exact lot size** for every trade (e.g., always `0.10`). This ignores changes in balance/equity and doesn’t adapt to volatility.

Use Fixed when you want **full manual control** (testing, strict money management rules), but be aware it also removes the EA’s dynamic risk adjustments.

***

#### 3) Percentage-based sizing (semi-manual)

You tell the EA to size trades based on a **fixed % of Balance** or a **fixed % of Equity**. The EA then calculates the lot size needed to match that allocation.

This scales trade size as your account changes, but it’s **not a stop-loss**. If set too high, it can create oversized positions and fast drawdowns—especially when Recovery is involved.
{% endhint %}

{% hint style="warning" %}

### Important behavior notes (so settings don’t “fight” each other)

* **Auto lot size multiplier** only applies in **true Auto mode** (i.e., when you are *not* using Fixed Lot or other manual sizing overrides).
* **Max Auto Lot Size** is your “seatbelt” for Auto: even if the EA wants to open bigger, it will cap at your limit.
* Any manual sizing method (Fixed / % Balance / % Equity) makes your exposure more rigid, so you’re taking more responsibility for making sure lot sizes match your account and risk tolerance.
  {% endhint %}

{% hint style="success" %}

### Quick recommendations

* **Most users:** Auto + Multiplier (start at `1.0`) + optional **Max Auto Lot Size** cap.
* **Testing / strict control:** Fixed Lot Size.
* **Portfolio-style risk scaling:** % of Balance or % of Equity (advanced—use conservatively).
