Forex trading explained: currency pairs, pips, spreads, leverage and risk
Forex is not simply a chart that moves 24 hours a day. A currency pair compares two economies, the instrument may be leveraged, execution may be dealer-based, and Indian residents must also check whether the platform and transaction are permitted.
Direct answer
Direct answer
Forex trading means taking exposure to the exchange rate between two currencies, such as EUR/USD or USD/INR. A good forex process combines pair mechanics, spread and financing costs, leverage, macroeconomic drivers, technical structure and platform/regulatory checks. For Indian residents, RBI says permitted forex transactions must be conducted with authorised persons and, when executed electronically, through authorised ETPs or recognised stock exchanges under the applicable rules.
Key takeaways
- • Every forex quote is a relationship between a base currency and a quote currency.
- • Pips, spreads, financing and slippage convert chart movement into real trading economics.
- • Leverage can make a small exchange-rate move a large account move.
- • Interest-rate expectations, inflation, growth and central-bank policy are major macro inputs.
- • Technical analysis should be combined with the economic calendar because data releases can rapidly change volatility.
- • Indian residents should verify both the permitted transaction and the authorisation status of the person/platform with RBI sources.
DeepScreen original framework
What this guide adds
The DeepScreen PAIR framework—Platform, Asset relationship, Instrument costs, Risk—keeps forex analysis grounded in both the chart and the legal/execution structure behind the quote.
Use PAIR before trading a currency pair
Forex analysis has four layers: Platform, Asset relationship, Instrument costs and Risk.
| Layer | Question | Why it matters |
|---|---|---|
| Platform | Is the venue/person authorised for this transaction? | Counterparty, legal and withdrawal risk |
| Asset relationship | What drives both currencies? | A pair is relative, not a one-country bet |
| Instrument costs | Spread, commission, financing, lot size? | Small costs matter in frequent trading |
| Risk | Leverage, stop, event risk, position size? | FX moves can be amplified by margin |
How currency pairs work
The first currency is the base and the second is the quote. The quoted price says how much quote currency is required for one unit of the base currency.
If EUR/USD is 1.1000, the quote convention means one euro is priced at 1.10 US dollars. If EUR/USD rises, the euro has strengthened relative to the dollar under that quotation. USD/INR works the same way: a higher quote means more rupees per US dollar.
Pips, spreads and lot size
The chart move is only one part of the trade; position size and transaction cost determine its monetary effect.
| Term | Meaning | Trading implication |
|---|---|---|
| Pip | Conventional small unit of pair movement | Used to express move and stop distance |
| Bid | Price at which the dealer/market buys | Relevant when selling |
| Ask | Price at which the dealer/market sells | Relevant when buying |
| Spread | Ask minus bid | Immediate transaction cost |
| Lot/contract size | Amount of currency represented | Determines pip value and exposure |
| Financing/swap | Cost or credit for carrying exposure | Can accumulate over multi-day positions |
Why forex leverage deserves special attention
Margin can make a very small currency move produce a large percentage gain or loss on account equity.
The CFTC warns that OTC forex uses margin and that leverage amplifies both gains and losses. Its customer advisory also notes that in dealer-based OTC forex, the customer may be trading directly against the dealer rather than on an open exchange. [2]
- • Calculate full notional exposure, not only margin posted.
- • Know the broker or exchange's maintenance-margin rules.
- • Do not use liquidation or margin call as the planned exit.
- • Size positions using stop distance and realistic slippage.
- • Treat leverage offered by an unfamiliar offshore platform as a due-diligence issue, not a benefit by itself.
What moves a forex pair?
FX markets constantly reprice the relative outlook for two currencies.
Because the price is relative, strong data in one country can have little effect if the other side of the pair improves even more. This is why forex analysis should compare the two economies and policy paths rather than reading each currency independently.
- • Central-bank policy and expected interest-rate paths.
- • Inflation and inflation expectations.
- • Employment, growth and business-activity data.
- • Trade and capital flows.
- • Political and geopolitical risk.
- • Broad risk sentiment and demand for funding or safe-haven currencies.
How to combine DeepChart with forex fundamentals
Use the chart to define structure and risk; use the economic calendar to identify events capable of changing that structure.
- • Define the higher-timeframe trend and major support/resistance.
- • Use the trading timeframe for entry structure and invalidation.
- • Measure current volatility before choosing stop distance.
- • Check momentum and divergence, but do not let one oscillator overrule price structure.
- • Review the upcoming central-bank and high-impact data calendar before holding through an event.
- • After a major release, let spread and volatility normalize before assuming old technical levels behave the same way.
Forex trading in India: check RBI authorisation before the chart
For Indian residents, platform and transaction eligibility are part of risk management, not an afterthought.
RBI's forex FAQ says resident persons may undertake forex transactions only with authorised persons and for permitted purposes under FEMA. It says permitted electronic forex transactions should be undertaken only on RBI-authorised ETPs or recognised stock exchanges—NSE, BSE and MSE—under the applicable terms. [1]
RBI also states that its Alert List is not exhaustive and that a platform not appearing on the list should not automatically be assumed to be authorised. Authorisation should be verified against RBI's authorised-person and authorised-ETP information. [1]
The same FAQ says resident individuals cannot use the Liberalised Remittance Scheme to remit margin overseas for online forex trading. Rules can change, so check RBI's current material before funding an account. [1]
Common forex fraud warning signs
Guaranteed returns and withdrawal obstacles are stronger warning signals than a professional-looking charting platform is a trust signal.
The CFTC advises checking dealer registration and disciplinary history, warns about unregistered offshore dealers found through social media, and notes that fraudulent platforms may demand additional payments before allowing withdrawals. [2]
- • Guaranteed or unusually consistent returns.
- • Pressure to deposit quickly or move to private messaging.
- • No verifiable regulator registration or physical presence.
- • Unusually high leverage marketed as a reason to trust the platform.
- • Crypto-only funding without clear legal/entity information.
- • Requests for extra 'tax', 'unlock' or 'verification' payments to release your own withdrawal.
FAQ
Common questions
- What is a pip in forex?
- A pip is a conventional unit used to describe a small price change in a currency pair. Its money value depends on the pair, position size and account currency.
- What is the spread in forex?
- The spread is the difference between the bid and ask price. It is one component of trading cost and can widen during illiquid periods or major news.
- Why is leverage common in forex?
- Major currency pairs often move in relatively small percentage increments, so margin is used to create larger economic exposure. The same leverage that magnifies gains also magnifies losses.
- Which forex timeframe is best?
- There is no universal best timeframe. Match the chart interval to the holding period and use a higher timeframe for context. Shorter intervals contain more noise and are more sensitive to spread and execution.
- Is online forex trading legal in India?
- Indian residents can undertake permitted forex transactions under FEMA, but RBI says they must use authorised persons and, for electronic execution, authorised ETPs or recognised exchanges under the applicable rules. Do not assume any global trading website is permitted for an Indian resident.
- Can DeepChart analyze EUR/USD and USD/INR?
- Yes, DeepChart includes supported forex symbols such as EUR/USD and USD/INR where data is available. Its technical reading is educational and does not replace platform, regulatory or macroeconomic due diligence.
