I've noticed that many beginners in crypto trading make the same mistake — opening a position without thinking about where to close it. That’s why stop loss and take profit are not just tools, but rather insurance against catastrophic losses and a way to lock in profits once they’re in your pocket.

First, you need to honestly determine how much you're willing to lose on a single trade. Most professional traders follow the rule: no more than 1-2% of total capital on one position. It sounds conservative, but this approach allows you to trade for years rather than burning out in a month.

Next, support and resistance levels come into play. These are points on the chart where the price usually reverses or bounces. When entering a long position, it’s logical to place the stop loss just below the support level, and the take profit somewhere near resistance. For a short, it’s the mirror image: stop above resistance, profit near support.

But here’s where the most interesting part begins. Simply setting a stop and a profit target is only half the job. The key is the risk-to-reward ratio. I usually stick to a 1:3 ratio, meaning potential profit should be at least three times greater than the possible loss. Otherwise, the math of trading simply doesn’t add up.

When calculating the stop loss, I determine the level at which the loss becomes unacceptable — say, 1% of capital. Accordingly, I set the take profit so that the potential gain is 3% or more. In practice, it looks like this: if I enter a position and am willing to lose $5, then the profit target should be at least $15.

Technical indicators are helpful here. Moving averages help see the trend through the noise of price fluctuations. RSI shows when an asset is overbought or oversold. ATR is especially useful for setting stop losses because it accounts for the volatility of a specific asset — on a volatile market, stop losses should be placed further away.

Let’s look at a concrete example. Suppose I enter a long position at $100. Support is at $95, resistance at $110. I place the stop loss at $95 — a risk of $5. The take profit at $115 — a profit of $15. The 1:3 ratio is maintained, so the trade makes sense.

For a short, the logic is the same. Entry at $100, resistance at $105, support at $90. Stop at $105 (risk of $5), profit at $85 (profit of $15). Everything is symmetrical.

In the end, properly calculated stop loss and take profit are the foundation of stable trading. You need to analyze support and resistance levels, monitor indicators, and maintain the risk-to-reward ratio. And most importantly — don’t ignore these levels when the price reaches them. The market is constantly changing, so periodically review your strategies and adapt them to current conditions.
