Yes this makes sense, this has given me more understanding thanks
The leavage is concerned with the normal value of a unit of the currency pair you are working with a leavage determins how much of your account balance is resserved against your open position as a kind of deposit.Remember the higher the amount the lesser the money rserved.
Leverage is borrowed money that your broker provides you to increase your ability trade. Availing leverage means that When you open a trade, you put some amount of money and the rest will be put by your broker, it depends on what kind of leverage you are using.
For example, if you choose 1:100 leverage, so for every 1 dollar you put you will get 100 from your broker.
So what do you think, is leverage useful or harmful?
You would be better off calculating the leverage on the single trade. Letâs say you deposit 1000.
You open 0.1 standard lot for a tot exposure of 10k. In this case if you havenât other position opened you are leveraging just 10x. ( even if your broker is giving you 30x or 100x )
For risk calculation, as many already said, use your balance. Not the exposure.
If you need something I am here 
Both. Itâs useful at small amounts as you can open larger positions than what your account size is. However if you get too much then the likelihood is youâll open a trade with too large a size and then risk more of your account than you should be. This results in blown accounts.
Trading leverage is a tool that allows you to invest for a higher nominal value than the value of your resources used.
It is necessary to understand that the variations in the prices of the currency pairs are often very low, compared to other assets such as stocks. Without leverage, it would be very difficult to make a profit, even if you have consistent investment capital.
It is hard to determine the best ratio of leverage you should use, as it mainly depends on the traderâs strategy and the actual vision of upcoming market moves.
leverage should be used wisely and wisely as your losses are also affected by this tool
If youâre a beginner keep the leverage low. In my opinion no more than 1:50. You can increase it gradually as you gain experience.
Leverage in Forex is basically a loan from your broker.
If your leverage is 100:1, it means you can trade 100 times more than you have. So, for every 1 dollar you have, you can trade 100 dollars.You do not have to pay the full amount for taking a position but a portion of it.
For example you need $50000 to take a long position in EUR/USD and the leverage provided to you is 1:100, you only need $500 in your account to take that position. Rest will be provided by the broker. This can vary from 50:1, 100:1 or 200:1 or more depending on the broker and the size of your trading position.
Leverage will boost your margin to trade more number of lots, it is a process in which an investor borrows money in order to invest; so if the leverage is 50X it means trader can trade $12500 by depositing $250 in his account.
