On this account, I will be utilizing a 1 Lot position size. However, please note that you have the flexibility to adjust the position size according to your risk appetite.</p><p>If you prefer a lower demo account size, you can decrease the lot size accordingly. For instance, with a 2.1 demo account, the maximum position size would be 0.5, and the amount to add would be 0.1. The choice is yours, and I encourage you to select the sizing that suits your testing needs.</p><p><br></p><p><br></p>
