What is a safe margin level?

Hi, I would like to know what is a safe margin level and how do I calculate how much I can put into a new trade in order not to go too low on the existing margin level?

Utilised Margin level depends on your leverage. You can easily test it by entering a position of 1000units, 5000Units, 10,000units or 50,000units. Just check how much margin it eats into you available margin. My recommendation is not to exceed 10%

Hello,
In order to calculate the margin requirement and how much you could put into a trade, you could use the following formula:
No. of lots * current price * Margin in %.

You could try first in demo environment and I agree with Aphahavoc that you could test with smaller sizes such as 1 micro lot.

Use a margin and pip value calculator. Once you know the value you are risking per pip then, the larger your stop loss, the more money you are risking on the trade. The margim is the amount of money you need in the account to take the trade. read my replies to questions above as they answer your question as well.
