• FX = Foreign Exchange — trading one currency against another (USD/JPY, EUR/USD, etc.).
  • Leverage amplifies both profits and losses; sizing matters more than entry.
  • Spread (bid-ask difference) is your transaction cost — narrow spreads compound over time.
  • For limited starting capital, prop firms are an alternative to funding a personal account.

FX is the largest financial market in the world by daily volume. For retail traders, it means buying one currency while simultaneously selling another — prices are quoted in pairs because every trade involves two currencies.

What FX actually is

When you trade USD/JPY, you’re trading the rate at which dollars exchange for yen. Profit comes from movement in that rate.

Unlike stocks, FX has no central exchange. Trades route through interbank networks and broker liquidity pools.

Key concepts to learn first

Four to start with:

  • Currency pair — the quote (USD/JPY, EUR/USD). The first currency is the base, the second is the quote.
  • Leverage — typical caps run 1:25 in Japan, up to 1:1000 with overseas brokers. Higher leverage amplifies losses, not just gains.
  • Spread — the gap between bid and ask. Tighter spreads cost less per trade.
  • Swap — overnight interest rate differential between the two currencies. Can be positive or negative depending on direction.

How to start

The standard sequence:

  1. Choose a broker (or a prop firm if you want to trade firm capital).
  2. Open an account and complete KYC (know your customer — identity verification).
  3. Demo-trade for several weeks before going live.
  4. Start with the minimum lot size when you do trade live.

Limited capital? Consider a prop firm

If your starting capital is small, prop firms let you trade firm capital ($5K–$2M depending on plan) after an evaluation fee. For many traders this is a faster path than slowly compounding a small personal account, though the evaluation isn’t free and pass rates are reportedly 10–20%.

Risks to flag

FX is leveraged and speculative. Losses can be rapid, and even disciplined traders take losing streaks. There are no guarantees of profit. Treat FX as a skill to develop slowly, not a shortcut to capital.
