What happens when you press Buy

Basics: how a trade and an account work3 min read
What you learn in 3 minutesA trade looks like one action on a chart, but it is really four steps: the order leaves your platform, it gets filled at a price, it becomes an open position, and it ends when you close it. Each step is where a specific cost attaches, so knowing the steps tells you what you are paying for. We use EUR/USD around 1.0850 and a standard lot to show the money in pesos.

The mistake people make here

Many beginners treat the Buy button as the whole trade and forget that the position stays open until they close it. They watch the chart move but do not check the spread, commission or swap that attach to the entry, the open position and the exit. The fix is to write down the four steps before pressing Buy, and to check what the broker charges at each step. If a cost is not clear, ask the broker or check the fee schedule.

If one pip on one standard lot of EUR/USD is 10 units of the quote currency, what is the pip value in pesos when the conversion rate is ₱58 to 1 unit?

10 units x ₱58 = ₱580 per pip.

You open a position at 1.0850 and close it at 1.0860. How many pips did the price move?

1.0860 - 1.0850 = 0.0010, which is 10 pips.

Using the pip value from the first question, what is the gross result of that 10-pip move on one standard lot?

10 pips x ₱580 = ₱5,800 before any spread, commission or swap.
