What is trading and how does it work

Trading is the active opening and closing of positions over a shorter horizon than investing, with a clearly defined thesis and quantified risk. Before choosing a setup, choose the instrument — CFDs, stocks, futures, and crypto differ in cost, leverage, and oversight. Position size is calculated from the risk budget and stop-loss distance, not from the leverage slider.

What this lesson covers and who it is for

This lesson explains what trading is, how it differs from investing, and what you must decide before opening your first position. It is designed for someone who has not yet traded on a live account and wants to start from zero: instrument, costs, leverage, and per-trade loss limit. There are no signals or ready-made setups here — there is a decision sequence and a formula for position size that keeps a string of losses survivable.

The printable version of the risk protocol is in the Method and artifacts section.

If you are switching from a demo account to a live account, the hardest part is usually not the strategy; it is the position size and the stop-loss distance. A strategy that looks profitable on a demo account can destroy a live account if the position size is too large for the stop-loss distance. This lesson gives you the order of decisions that prevents that outcome.

Trading and investing — where is the boundary

Investing means buying assets with a horizon of months or years and participating in what the company, fund, or economy does. Trading means actively managing a position over a shorter horizon — from minutes to weeks — with a clear invalidation (stop) and quantified risk. Neither approach is inherently better; they differ in tools, costs, and what you must monitor every day.

In Poland many people run both approaches on one account and it works as long as the roles are separated: one part of capital is calm allocation, the other is training capital with a hard loss limit. A broader comparison of both paths: trading vs investing.

Instrument before setup: CFD, stocks, futures, or crypto

Before you look at the best setup on M15, answer the question of what you are trading. The same idea on a chart has different costs, different leverage, and different oversight depending on the instrument. One of these classes is currency pairs: if you want to start with them, what this market is and who your counterparty is, the lesson What is forex explains.

The choice of instrument changes the entire risk profile. A CFD on a stock gives you leverage but also overnight financing and a counterparty risk. A futures contract gives you standardised leverage and expiry but requires margin management. Crypto gives you 24/7 liquidity but adds exchange and custody risk. Choose the instrument that matches your risk budget and availability to monitor positions. Asset classes themselves are compared in the lesson Instruments and markets; the next step after choosing an instrument is order types.

Position sizing

Position size should come from the risk budget and the stop-loss distance, not from the leverage slider. If you risk 1 per cent of capital per trade and your stop is 2 per cent away from entry, your position size is fixed by those two numbers. Leverage only scales the notional exposure; it does not change the economic risk if the stop is fixed.

1R (risk budget) = trading capital × risk percentage per trade
position_size    = 1R / (stop distance × value of one point per 1 lot)

The formula is simple: position size equals risk budget divided by stop distance. If your account is 10,000 units, you risk 100 units per trade, and your stop is 2 per cent away from entry, your position size is 5,000 units notional. A 10x leverage slider does not change that economic exposure; it only changes the notional amount. If the stop is hit, you lose 100 units regardless of leverage.

Step by step:

1. Set the trading capital. This is the amount set aside for trading, not all your savings; losing it must not change your life plans.
2. Set the risk percentage per trade. The starting point is 1 per cent, the usual upper bound is 2 per cent.
3. Calculate 1R in your account currency. Trading capital multiplied by the risk percentage.
4. Measure the stop distance in the instrument’s price: pips, points, or currency per share.
5. Read the value of one point per 1 lot or 1 contract in your account currency. This is a number from your broker’s table and does not depend on your position size. Check with your broker.
6. Divide 1R by the distance multiplied by the point value per 1 lot. The result is the position size in lots or contracts at which the stop costs exactly 1R.

Illustrative example: trading capital $10,000, risk 1 per cent, so 1R = $100; stop distance 20 pips and the value of one pip per 1 lot is $5 (illustrative number). Then position size = 100 / (20 × 5) = 1 lot. All numbers in the table are illustrative — your values depend on the symbol, contract size, and account currency, so check with your broker.

The starting point is 1 per cent risk per trade, 2 per cent is the usual upper bound (The 1–2 per cent rule); the mechanics of the stop and the R multiple are in Stop-loss and R-multiple.

From demo to live

The hardest part of the transition is usually not the strategy; it is the position size and the stop-loss distance. A strategy that looks profitable on a demo account can destroy a live account if the position size is too large for the stop-loss distance. The demo environment does not charge you for spread, swap, or slippage in the same way a live account does. When you go live, start with the smallest possible size and the same stop distance you used in demo. Record every trade with cost and outcome. After twenty live trades, compare the results with the demo results. If the live expectancy is lower by more than the measured costs, the strategy may still be valid but the execution or sizing is wrong.

Broker, costs, and leverage

Costs are the reason most traders lose money even with a good strategy. Spread, commission, and overnight financing add up. A broker that offers zero commission usually makes money on the spread or the swap. A broker that offers high leverage makes money when you over-size positions and get stopped out. Before you open an account, check the spread on the instrument you want to trade, the commission per lot or per trade, and the overnight financing rate. Note the percentage risk from the broker’s risk banner together with the date, because it is a property of the broker, not the market.

Entry and exit cost is spread, commission, overnight swap, and slippage. Express it as a fraction of R to compare instruments:

cost_in_R = round-trip cost in USD / 1R

If the cost is 0.2R, you give away one fifth of the risk budget before the market does anything in your favour (Round-trip costs). Cost also raises the break-even threshold — at a reward-to-risk ratio of 2 to 1:

required_winrate = (1 + cost_in_R) / (1 + R:R)

Without cost that is about 33.3 per cent; at a cost of 0.2R it rises to 40 per cent. Both are illustrative numbers for R:R = 2.

Do not treat the percentage here as a constant fact about the market: it is a property of a specific broker on a specific date and changes with later updates. Read it, then write it down with the context.

This entry does not predict your results; it is a starting point for discipline. What counts here is the document and the date, not an anecdote from social media.

Common mistakes

• Choosing an instrument based on marketing rather than cost structure and counterparty.
• Using the leverage slider to decide position size instead of the risk budget and stop distance.
• Skipping the demo-to-live transition and starting with a size that is too large for the stop.
• Changing the strategy after a few losses instead of keeping the process fixed.
• Ignoring currency conversion and tax treatment when calculating real returns.

When the market says do not trade

1. You do not know the cost of entry and exit for your instrument. You do not know the price of taking part in the game, so you have not yet made an investment decision.
2. You cannot point to the level that invalidates the scenario. No invalidation means no stop distance, and without it you cannot calculate position size.
3. Your plan for the session is one trade meant to win back a loss. That is not a plan, it is a reaction to the previous result.
4. Risk per trade grows during the session — for example, after two losses you increase position size. Changing the rules mid-game means the rules were not there before.

Key points

• Trading vs investing: horizon, thesis, risk quantification
• Instrument choice: CFD, stock, futures, crypto — costs and leverage differ
• Position sizing from risk budget and stop distance
• Demo to live: start small, measure costs, compare after twenty trades
• Costs and leverage are broker-specific; note them with the date

Glossary

Review checklist

Before your first live trade, check the following:

• Instrument class chosen and documented
• Counterparty and custody structure understood
• Spread, commission, and overnight costs recorded
• Position size calculated from risk budget and stop distance
• Daily loss limit set and enforced by a tool
• Tax treatment checked for your jurisdiction

This checklist is not optional. Skipping any of these items turns trading into gambling.

Nothing here promises guaranteed profits, a holy grail, or signals for tomorrow. Financial decisions are yours, made after understanding the costs and the risk at a supervised broker — for example under the supervision of the KNF or another European Union authority.

Common questions

Can I combine trading and investing in one account?

Technically yes, but psychologically it often hurts. Separate the goals: a long-term ETF and short setups with a stop. Otherwise an investment becomes a position without a plan after a series of losses.

Does this course provide entry signals?

No. You learn the process: instrument, order, risk, plan. Signals from a chat group will not replace expectancy and a risk limit.

Where do I get the percentage of losing accounts?

From the current risk warning at your CFD broker — record the number and the date. Do not rely on a remembered value from articles, because the banners are updated.

Why measure risk and cost if this is educational material?

Because a chart shows potential, not the result after costs. Without 1R and without cost expressed as a fraction of R, you cannot tell a strategy that makes money from one that only looks good in screenshots. Measurement is the only way to assess your own process instead of someone else's.
