INR account advantage

With an INR-denominated account on FxPro, your risk amount stays in rupees throughout. No unnecessary bank conversion on deposit: a ₹50,000 transfer arrives as ₹50,000. With a USD account funded from an Indian bank, your bank typically charges 1–3% on every international transfer — that's ₹500–₹1,500 lost before you place a single trade.

FxPro is FCA regulated — client funds are segregated and held in top-tier banks. Indian traders should review applicable RBI guidelines before trading offshore forex products.

How to use this calculator

01

Select your instrument

Choose from forex pairs (including USD/INR and other INR crosses), metals (XAU/USD gold, XAG/USD silver), indices (NAS100, US30) or crypto (BTC/USD). The calculator applies the correct pip size and contract specifications for each instrument class automatically.
02

Set account balance and risk %

Your balance is the total account equity in INR. Risk % is the portion of that balance you are willing to lose if your stop-loss is hit. Most experienced traders stick to 1%. The calculator converts this into an exact rupee amount at risk, then works backwards to determine the correct lot size.
03

Enter your stop-loss distance

Input the distance in pips (or points for indices) between your entry price and your stop-loss level. The calculator divides your rupee risk amount by the pip value to arrive at the correct lot size. A wider stop-loss results in a smaller position size to keep risk constant.
04

Review R:R scenarios and streak simulation

The R:R table shows your potential profit at 1:1, 1:1.5, 1:2 and 1:3 risk-reward ratios for the calculated position size. The streak simulation stress-tests your account balance over a run of consecutive losing trades — the single most important risk management check before placing any trade.

Frequently asked questions

What is position sizing?

Position sizing is the process of calculating how many lots to trade so that a losing trade costs exactly the rupee amount you planned to risk. Correct position sizing keeps your risk consistent across different pairs, instruments, and stop-loss distances.

How does the lot size formula work?

Lots = (Account Balance × Risk%) ÷ (Stop-Loss pips × Pip Value per lot). For USD/INR, the pip value varies with the current exchange rate — the calculator fetches live rates to keep results accurate. For other pairs, pip value is similarly adjusted to reflect real market conditions.

How does this work for gold (XAU/USD)?

Gold uses 100 troy ounces per standard lot with a pip size of $0.01, giving a pip value of $1.00 per standard lot. Converted to INR at the prevailing USD/INR rate, for example at ₹83.50, that is ₹83.50 per pip per lot. For a ₹5,000 risk with a 50-pip stop: lots = ₹5,000 ÷ (50 × ₹83.50) = 0.0012 lots. Use micro-lots (0.001) for gold when trading smaller accounts.

Why does lot size change on each losing trade in the simulator?

The simulator applies proportional risk — each trade risks the same percentage of the current account balance rather than a fixed rupee amount. As the balance falls after consecutive losses, the rupee amount at risk falls proportionally and lot sizes shrink accordingly. This approach is how professional traders prevent a losing streak from wiping out their account.

What does 'spread cost' mean?

Spread cost is the rupee cost of entering a trade based on your lot size: spread pips × pip value per lot. This amount is paid to the broker the moment you enter the trade, before price has moved in your favour. A wide spread on a large position can represent a significant immediate cost that price must overcome before the trade becomes profitable.

What is the break-even win rate in the R:R table?

The break-even win rate is the minimum percentage of trades you need to win to remain profitable at a given risk-reward ratio. At 1:2 R:R, you only need to win 33% of your trades to break even. At 1:3 R:R, just 25% wins are sufficient. This is why a favourable R:R ratio often matters more than having a high win rate.
