## HK50 Lot Size Calculator

**HK50 Lot size calculator** have several fields that needs to be entered in order to calculate lot size:

**Instrument****Deposit Currency****Stop Loss**- in pips or in money

**Account Balance****Risk per trade**

These fields you need to enter to calculate lot size.

When you do that you get the result as:

**Lot size**- the lot size you need to enter into the Volume field inside new order window

**Units (trade size)**- number of units of base currency. For Forex currency pairs you have
**100,000 units**for 1 lot - For
**commodities or indices**you need to check specification sheet from your broker for that symbol

- number of units of base currency. For Forex currency pairs you have
**Money at Risk**- How much money you are risking with the lot size calculated

### Position Size Calculator

HK50 position size calculator is also called lot size calculator because position or lot is the same. Lot defines how many units of base currency you will use and position tells you how large the volume you will use.

When you use volume and number of units into the calculation it is the same variable we are talking about.

So when calculating the HK50 lot size of a trade you are calculating HK50 position size.

**NOTE**: for the HK50 the contract size is defined as 1 lot = 1 unit of base currency. That means the value of a 1 pip will be equal to:

For deposit currency which is equal to quote currency, **USD**:

**Pip value = Pip size x lot size units**

1 Pip = 0.01 x 1 = $0.01

### How to Use Lot Size Calculator

In this example you can see that I have defined all variables inside lot size calculator:

- Instrument: HK50
- Deposit Currency: USD
- Stop Loss (pips): 200
- Account Balance: 10,000
- HK50 1 Pip Size: 0.01
- Risk: 2%
- Contract size(Units per Lot): 1 (
**note**: 10 units = 10 lot)

These are variables that you need to define:

**Instrument**: HK50**Deposit Currency**: USD**Stop Loss**(pips): 200**Account Balance**: 10,000**Risk**: 2%

The HK50 1 pip size and contract size is already defined by the Forex instrument.

#### Calculate Lot Size for HK50

The Lot size calculator takes these values and first calculates the Lot size needed to be used in order to get risk to 2%.

**Risk = 2% out of $10,000 = $200**

**Stop Loss = 200 pips**

**Pip value = $0.01 per 1 lot**

I am using 10 units as a contract size so I am using 10 lots which is $0.1 per 1 pip.

**Stop Loss in $ = 200 pips x $0.1 = $20 per 10 lot**

Now, we have a $20 stop loss if we use 10 lot. But, in order to get to 200 which is 2% risk as I have defined I need to multiply Stop Loss with 10. That means I need to use Lot size 10x higher than it is used in calculations and that was 10 lot.

**Lot size = 10 lot = $0.1/pip -> 10 lot *10 = 100 lot**

**Lot size = 100 lot = $1/pip**

**Stop Loss in $ = 200 pips x $1 = $200 per 1 lot**

This is how we have lot size calculated in this example.

#### Calculate Units (trade size)

When you have Lot size = 0.1 this is easily converted to the number of units.

**1 Lot = 1 unit of base currency.**

**0.1 lot = 0.1**

And this is how we got the number of units for the 0.1 lot.

## Conclusion
