How to Trade the Market: Basic Concepts to Get Started

Astron Team · 09/24/2026 · 4 min read

Before opening your first position, it's worth understanding what happens behind the click on buy or sell. Trading isn't guessing whether a price will rise or fall: it's deciding, with numbers in hand, how much you're willing to risk to try to capture a move, and exiting the trade in a planned way, whether winning or losing.

Those who skip this step tend to repeat the same script: entering without knowing how much they can lose, increasing the bet size after a loss to recover quickly, and disappearing from the market within a few weeks. The concepts below are what separate a trade with a method from a bet disguised as analysis.

What you're actually buying or selling

By buying an asset, you're betting the price will rise from the moment of entry; by selling, you're betting on the opposite move. In either case, the trade's result is the difference between the exit price and the entry price, multiplied by the quantity traded. It sounds obvious, but this simple math is what should be behind every decision, not the feeling that the asset is about to take off.

Define the position size before entering

The first number a beginner should calculate isn't the profit target, but how much they're willing to lose on that specific trade. A common reference is to risk at most 1% to 2% of available capital per trade.

Example with real numbers: a trader has R$ 8,000.00 available and decides to risk 2% per trade, or R$ 160.00. The asset is trading at R$ 40.00 and the stop, set by technical analysis, is at R$ 38.00 — a distance of R$ 2.00 per unit. Dividing the total risk by the risk per unit (R$ 160.00 ÷ R$ 2.00) gives 80 units. That represents a R$ 3,200.00 position, or 40% of capital, with a previously known maximum loss of R$ 160.00 if the stop is hit.

Entry order, stop, and target: the tripod of every trade

Every planned trade has three prices defined before the entry, not after:

• Entry price: where the analysis indicates the risk-reward ratio pays off.
• Protective stop: the point that invalidates the original idea and limits the loss.
• Exit target: where the profit is taken, preferably calculated to be worth at least double the risk taken.

In the earlier example, if the target is at R$ 44.00, the potential gain per unit is R$ 4.00 against a risk of R$ 2.00 — a 1-to-2 risk-reward ratio. That means, even winning fewer than half the trades over time, it's still possible to end up positive, as long as that discipline is kept trade after trade.

Learn from history before risking real money

Before trading with your own capital, it makes sense to test the method on a demo account or by reviewing past charts, noting each entry, stop, target, and result as if it were real money. The goal isn't to be right every time, but to confirm the logic is consistent and that you can follow it without changing the plan mid-trade out of anxiety.

It's worth keeping a simple journal of these simulated trades: date, asset, reason for entry, stop, target, and final result. After twenty or thirty entries, you can look at the whole set and answer a concrete question: did most of the losses come from the price genuinely going against the plan, or from you abandoning the plan too soon? That difference changes what needs fixing — the method or the discipline.

Common mistakes among beginners

• Entering the trade without knowing, before the click, how much you're willing to lose.
• Moving the stop further away after the price has already gone against the position.
• Increasing the size of the next entry to try to recover a previous loss.
• Trading several assets at once without controlling the account's total risk.
• Confusing a winning streak with proof that the method is correct.

Trading involves real risk of capital loss, and no concept here eliminates that risk — they only organize how you deal with it. A platform like Astron is meant to execute the plan you've already defined, not to replace it. Start small, log every trade, and only increase position sizes when the process, not a single result, shows it's working.
