Demo accounts: what they teach and where they lie

Open a demo chart of EUR/USD. You will see a line that moves up and down. The price might sit near 1.0850. That number means one euro costs about one dollar and eight and a half cents. The chart does not show pesos. It shows the price of one currency against another. Your account holds pesos, so every pip you win or lose must be turned into pesos before you can judge it.

Look at the smallest step the price takes. On EUR/USD that step is usually 0.0001. People call that one pip. If the price moves from 1.0850 to 1.0851, it has moved one pip. A move from 1.0850 to 1.0870 is twenty pips. The demo chart draws those moves honestly. The arithmetic you do on them is the same arithmetic a live account uses.

The chart also shows a bid price and an ask price. The ask is slightly higher than the bid. The gap between them is the spread. On a demo, the spread is often fixed and small. On a live account it can widen when the market moves fast. The chart may not show that widening. You see only the last traded price, not the price you will actually get.

When you click buy on a demo, the platform fills your order at the price on the chart. That price is clean. It is the exact number you saw. The demo does not need to find someone willing to sell to you. It just writes the trade into its own book. So the fill looks perfect every time. That perfection is a teaching tool for the platform, not a promise about the market.

In a live account, your order goes out to real participants. If the market is calm, you may get the price you saw. If the market is fast, the price can move before your order arrives. Your fill might be two pips worse, or five, or more. That gap is called slippage. On a demo, slippage is usually zero. On a live account, it is a real cost that changes your result.

The demo also fills every order instantly. In a live market, an order can be delayed or partly filled. You might get only half the lots you asked for. The demo never shows that. So the demo teaches you the buttons and the pip arithmetic. It does not teach you what happens when the market is moving quickly and your order is one of many.

On EUR/USD, one pip on one standard lot is ten units of the quote currency. The quote currency is the second one in the pair, so here it is the US dollar. That means one pip on one standard lot is ten dollars. But your account is in pesos. You need to convert those dollars into pesos using the current exchange rate. The demo platform often does this for you and shows the profit or loss in pesos.

Suppose the exchange rate is ₱54.25 for one US dollar. Then ten dollars is ₱542.50. That is the pip value for one standard lot. If you trade 0.10 lots, you divide by ten. The pip value becomes about ₱54.25. So a twenty pip move on 0.10 lots is twenty times ₱54.25, which is ₱1,085. The demo will show that number. The arithmetic is honest.

But the demo may round the pip value. It may also ignore the spread and commission. In a live account, you pay the spread on every trade. You may pay a commission too. Those charges reduce your profit or increase your loss. They vary between brokers. So the number on the demo is a starting point, not the final amount you would keep.
