Position Sizing with Lot Sizing


The general definition of lot size:


"Lot size refers to the quantity of an item ordered for delivery on a specific date or manufactured in a single production run. In other words, lot size basically refers to the total quantity of a product ordered for manufacturing."


But how does this apply to FOREX?

Currency Units tell us how much currency we are going to buy or sell in the market. Forex is commonly traded in specific amounts called lots, or basically the number of currency units you will buy or sell.

If you buy a currency with a 1 lot size you are purchasing 100,000 units of that currency.


Naturally, if you want to become a successful trader you must know this information and be able to apply it on a daily basis...


Don't panic though, we will explain it in detail soon enough, plus, we have lots of different resources to help you along the way...


The different lot sizes


How do lot sizes help my Trading?


The forex lot size that works well for you is really dependent on a number of factors based on how you want to trade.

You need to know how much money you will be trading with, this is called capital.

Risk management is key when using lot size as you need to be able to maintain your positions. you need to know how much of your capital you actually want to risk at any one time.

At Logikfx we would recommend no more than 3% but the decision is ultimately yours.

If you purchase too many units of a currency this may become overwhelming for your account and it will be shut down by your broker.


Leverage is a key factor in working out the best lot size for you as it allows you to effectively borrow money and inflate your capital allowing you to buy more currency, however, leverage can be very dangerous as we will explain further down the article...
