Swing and position trading
This lesson shows how to add the swap to the spread before you decide whether a multi-day idea is worth holding.
Overnight gap risk in multi-day positions
A trader in Mumbai held a USD/INR long position for three nights. The market closed on Friday at 83.2500. On Monday it opened at 83.1000, a gap of 150 pips against the position. The stop-loss order was set at 83.2000, but it was filled at 83.1000 because the market jumped over it. The loss was larger than planned.
Overnight gaps happen when the market is closed. News, economic data, or events in other time zones can move the price before your platform reopens. A stop-loss order does not protect you from a gap. It becomes a market order at the next available price, which may be far from your stop level.
The risk of a gap grows with the number of nights you hold. A trade held for one night has one gap risk. A trade held for ten nights has ten. You cannot know the size of a future gap. You can only decide whether the potential profit justifies that unknown risk. For many multi-day trades, it does not.
Swap calculation on the platform
Swap is the interest you pay or receive for holding a position overnight. It is based on the difference between the interest rates of the two currencies in the pair. For USD/INR, you are trading the US dollar against the Indian rupee. The swap rate is quoted by your broker and can be positive or negative. A negative swap means you pay; a positive swap means you receive.
The swap is applied each night at a set time, usually when the market closes in New York. On your trading platform, you can find the swap rate in the instrument specifications. It is often shown as points or as a percentage per year. For example, a swap of -0.5 points per night on one standard lot of USD/INR means you pay ₹5 per night, because one pip is ₹10 and 0.5 pip is ₹5.
Swap rates vary between brokers and can change daily. They also depend on the lot size and the direction of your trade. Before you hold a position overnight, check the exact swap rate on your platform. Multiply it by the number of nights you expect to hold. Subtract the total swap from your expected gross profit. If the result is not acceptable, do not hold.
Net profit after spread and swap
The spread is the difference between the bid and ask price. You pay it when you enter and when you exit. For USD/INR, a typical spread might be 2 pips. On one standard lot, that is ₹20 to enter and ₹20 to exit, a total of ₹40. The swap is added for each night you hold. So the total cost of a multi-day trade is spread plus swap.
Suppose you expect a 40 pip move in your favour. Gross profit is 40 pips x ₹10 = ₹400. Spread cost is ₹40. If you hold for three nights and swap is ₹30 per night, total swap is ₹90. Net profit is ₹400 - ₹40 - ₹90 = ₹270. If the swap were ₹140 per night, total swap would be ₹420, and the net result would be a loss of ₹60 before spread, and ₹100 after spread.
The lesson is simple: a multi-day trade must overcome both spread and swap. The longer you hold, the more swap you pay or receive. If the swap is negative, it eats into your profit. If it is positive, it adds to your profit, but that is not common for USD/INR. Always calculate the net amount before you decide to hold. If the net amount is not worth the risk, the trade is not worth holding.
Four days on USD/INR: 40 pips gross, ₹400, minus ₹90 swap
| Step | Amount | Note |
|---|---|---|
| Entry price | 83.2500 | the price at which the position is opened |
| Exit price | 83.2540 | the price at which the position is closed four days later |
| Price move | 0.0040 | 83.2540 minus 83.2500 |
| Pips gained | 40 pips | 0.0040 divided by 0.0001 |
| Position size | 1 standard lot | 100,000 units of USD/INR |
| Value per pip | ₹10 | 100,000 x 0.0001 = ₹10 per pip on one standard lot |
| Gross profit | ₹400 | 40 pips x ₹10 per pip |
| Swap charged per night | ₹30 | an illustration only; the actual rate varies between brokers |
| Nights held | 3 | the position is open for four days and three nights |
| Total swap | ₹90 | 3 nights x ₹30 |
| Net profit | ₹310 | ₹400 gross profit minus ₹90 swap |
The broker may also charge a spread at entry and exit, and may round the swap. Swap rates vary between brokers and can change daily, so always check the rate quoted on your platform.
Doing it once, step by step
You will now go through the steps to evaluate a multi-day trade on USD/INR, from checking the swap rate to calculating the net profit. Do this once for each trade idea before you enter.
- 01
Find the swap rate
Open your trading platform and look for the instrument specifications for USD/INR. Locate the swap rate for the direction you plan to trade. It may be shown as points per night or as an annual percentage. Write it down. Remember that swap rates vary between brokers and can change daily.
- 02
Estimate the holding period
Decide how many nights you expect to hold the position. This could be based on your analysis of the chart or a planned exit date. Be realistic: if you are unsure, use a longer period to be conservative. The number of nights directly affects the total swap you will pay or receive.
- 03
Calculate total swap
Multiply the swap rate per night by the number of nights. If the swap is quoted in points, convert it to rupees using the pip value. For one standard lot of USD/INR, one pip is ₹10. So a swap of 3 points per night is ₹30 per night. Total swap is that amount times the number of nights.
- 04
Add the spread
Check the current spread on your platform for USD/INR. It is the difference between the bid and ask price. Multiply the spread in pips by the pip value to get the spread cost in rupees. This cost is paid on entry and again on exit, so double it for a round trip. Add this to the total swap to get the total cost.
- 05
Subtract from expected gross profit
Estimate the gross profit from your expected price move in pips. Multiply by the pip value to get rupees. Subtract the total cost (spread plus swap) from the gross profit. The result is your net profit. If the net profit is negative or too small for the risk, do not take the trade.
- 06
Check for overnight gap risk
Consider the possibility of a price gap when the market is closed. A stop-loss order may not limit your loss if the market jumps over it. Think about upcoming news or events that could cause a gap. If the potential gap risk is high, you may decide to reduce your holding period or avoid the trade entirely.
The mistake most people make here
The common mistake is to look only at the price move and ignore the swap. A trade that gains 40 pips looks like ₹400, but three nights of swap at ₹30 a night leaves ₹310. If the swap were ₹140 a night, the same trade would end at a loss. Before holding overnight, check the swap rate on your platform and subtract the total swap from your expected profit. If the remaining amount is not worth the risk, the trade is not worth holding.Check yourself
A USD/INR position of one standard lot gains 25 pips and is held for four nights. Swap is ₹25 per night. What is the net profit in ₹?
Gross profit is 25 pips x ₹10 = ₹250. Total swap is 4 nights x ₹25 = ₹100. Net profit is ₹250 - ₹100 = ₹150.
If the same trade gains 10 pips instead of 25, and swap is still ₹25 per night for four nights, what is the net result?
Gross profit is 10 pips x ₹10 = ₹100. Total swap is ₹100. Net result is ₹100 - ₹100 = ₹0, before any spread.
Questions that come up next
What is an overnight gap and how does it affect a multi-day trade?
An overnight gap is a price jump between the close and the next open. It happens when news or data arrives while the market is shut. A stop-loss order cannot protect you from a gap. The order becomes a market order at the next price, which may be far from your stop level. The more nights you hold, the more gaps you face.
How do I find the swap rate on my platform?
Open the instrument specifications for USD/INR. The swap rate is often shown as points per night or as a percentage per year. It can be positive or negative. Check it before you hold a position overnight. Swap rates vary between brokers and can change daily.
Does a positive swap mean I make money on every multi-day trade?
No. A positive swap adds to your account each night, but it does not remove the risk of a price move against you. A large adverse gap can wipe out many nights of positive swap. The swap is only one part of the total cost. You must still subtract the spread and consider the gap risk.
Can I avoid swap by closing before the daily cut-off?
Yes. If you close the position before the swap time, usually when the market closes in New York, you do not pay or receive swap for that night. But closing early may mean you exit before your idea has time to work. You must weigh the saved swap against the lost opportunity.
How does the lot size change the swap amount?
Swap is charged per lot. A larger lot means a larger swap per night. For example, if one standard lot pays ₹25 per night, two standard lots pay ₹50 per night. Always check the swap for your actual lot size. The platform may show the rate per standard lot.
What is the difference between swing trading and position trading?
A swing trade holds for days or weeks. A position trade holds for longer, often months. Both pay swap each night. Position trades face more nights and therefore more gap risk. The cost structure is the same, but the scale is larger.
The words used on this page
- swap
- The interest you pay or receive for holding a position overnight. It is based on the interest rate difference between the two currencies in the pair. It is applied each night at a set time.
- spread
- The difference between the bid price and the ask price. You pay it when you enter and when you exit a trade. It is a cost that applies to every trade, not just multi-day ones.
- overnight gap
- A price jump between the market close and the next open. It happens when news or events move the price while the market is shut. A stop-loss order does not protect you from a gap.
- stop-loss order
- An order to close a position at a chosen price to limit a loss. It becomes a market order when triggered. In a gap, it may be filled at a much worse price than the stop level.
- standard lot
- A fixed position size used in forex trading. For USD/INR, one standard lot makes one pip equal to ₹10. Swap and spread are often quoted per standard lot.
- pip
- The smallest common price move in a currency pair. For USD/INR, one pip is 0.0001. On one standard lot, one pip is worth ₹10.
What to take away
- A multi-day trade pays swap each night on top of the spread. Subtract the total swap from your expected gross profit before you decide to hold.
- An overnight gap can jump over your stop-loss and turn a planned loss into a larger one. The risk grows with every night you hold.
- Swap rates vary between brokers and can change daily. Always check the rate on your platform for your lot size and direction.
- If the net profit after spread and swap is not worth the gap risk, the trade is not worth holding.
