Trading from a phone
What you learn in 3 minutesA phone screen shows about six inches of chart, and that single fact changes what a beginner can see before pressing buy or sell. This lesson works out which parts of a trading terminal survive on that screen and which do not, using USD/INR near 83.2500 and a pip value of ₹10 on one standard lot.
What fits on a 6-inch screen at USD/INR 83.2500
| Step | Amount | Note |
|---|---|---|
| Visible chart window on the phone | about 40 candles | a typical phone chart in portrait mode, schematic |
| Visible chart window on the desktop | about 200 candles | same instrument, same timeframe, wider screen |
| Distance to the stop, in pips | 20 pips | chosen by the reader, not by the app |
| Position size | 0.10 standard lots | one tenth of a standard lot |
| Value of one pip at 0.10 lots | ₹1 | ₹10 per pip on one standard lot, divided by ten |
| Risk if the stop is hit | ₹20 | 20 pips x ₹1 per pip |
The broker may round the pip value, quote a slightly different USD/INR price, and charge a spread or commission on top. These vary between brokers.
The mistake people make here
The common mistake is to trade the same size on the phone as on the desktop, because the order ticket looks identical. The ticket is identical, but the chart is not, so the reader is setting a stop without seeing the price levels that sit just off the screen. The fix is to zoom out first, note the nearest level that is out of view, and only then set the stop. If the stop has to sit inside the visible window to look safe, the position is too large for that screen.Check yourself
A reader trades 0.20 standard lots on USD/INR with a stop 15 pips away. What is the risk in rupees?
One pip on 0.20 lots is ₹2, because ₹10 per pip on one standard lot scales with size. 15 pips x ₹2 = ₹30.
The same reader moves to 0.05 standard lots with a stop 40 pips away. What is the risk?
One pip on 0.05 lots is ₹0.50. 40 pips x ₹0.50 = ₹20.
