1. What is the Spread?
The spread is the primary cost of doing business in the Forex market. It is the mathematical difference between the price you can buy a currency for and the price you can sell it for at the exact same moment. Think of it like a currency exchange booth at an airport; they buy your Dollars for one price and sell them back to you at a higher price—that “gap” is their profit. In Forex, the broker takes this spread to facilitate your trade.
In highly liquid pairs like the EUR/USD, the spread is usually very thin (often less than 1 pip). However, in “Exotic” pairs like the USD/ZAR, the spread can widen significantly, especially during South African news events or when the New York market closes. At TryBuying, we teach you that the spread is your “entry tax.” Because of the spread, every trade you open starts in a small negative. You must account for this cost before your trade can move into a profit.
2. Bid vs. Ask Price
To navigate the markets, you must understand the two-way pricing system. The Bid is the price at which the market is prepared to buy a currency from you (the price you get when you click ‘Sell’). The Ask is the price at which the market will sell to you (the price you pay when you click ‘Buy’). The Ask price is always higher than the Bid price. Beginners often get frustrated because they see the price hit their target on the chart, but their trade doesn’t close—this is usually because they are watching the “wrong” price line.
Standard charts in MT4/MT5 typically show the Bid price by default. If you are in a “Sell” trade, your exit (the Buy back) happens at the Ask price. This means the price on your screen needs to drop *below* your target by the width of the spread for the trade to close. Understanding this distinction prevents “ghost” stop-losses and helps you set more accurate targets.
3. Market Execution vs. Pending Orders
There are two ways to enter the market: reacting or planning. Market Execution is a “Buy or Sell Now” command. You use this when price action confirms your setup immediately and you are happy to take the current available price. While fast, the danger is that in a volatile market, the price might move a few pips between the time you click the button and the time the broker fills the order.
Pending Orders are for the disciplined trader. They allow you to set a “trap” at a specific price level. You are telling the platform: “If, and only if, the price reaches this exact level, open my trade.” This is the cornerstone of professional trading because it removes the emotion of chasing the market. You don’t have to sit at your screen all day; you simply set your orders and let the market come to you. At TryBuying, we advocate for pending orders as they ensure you only enter trades that meet your strict criteria.
4. Buy Limit vs. Buy Stop
Pending “Buy” orders come in two flavors, and choosing the wrong one is a common beginner mistake. A Buy Limit is used when you want to buy at a price *lower* than where the market is currently trading. You are expecting the price to drop to a “discount” or support level, bounce, and then head back up. It is a “buy the dip” strategy. It offers better pricing but carries the risk that the market might never drop low enough to pick up your order.
A Buy Stop is the opposite. You use it when you want to buy at a price *higher* than the current market value. This is typically used for “Breakout” trading. You are telling the broker: “I don’t want to buy now, but if the market shows enough strength to break through this resistance level, I want to go with the momentum.” While you are paying a higher price, you have the confirmation that the market is moving in your desired direction.
5. Sell Limit vs. Sell Stop
When you are looking to “Short” or Sell the market, you again have two choices. A Sell Limit is placed *above* the current market price. You are looking for the market to rally up to a specific resistance level where you believe it will “run out of steam” and turn back down. This allows you to sell at a “premium” price. It is the preferred method for mean-reversion traders who look for overextended moves to fade.
A Sell Stop is placed *below* the current market price. This is used when you believe that if the price breaks a certain support level, it will continue to crash lower. It is a “momentum” sell. For example, if the USD/ZAR is trading at 18.50 and you believe a break below 18.40 will lead to a massive drop, you place a Sell Stop at 18.39. Your trade only activates once the “floor” has broken, confirming the bearish pressure.
6. The Order Book Logic
To be a professional, you must stop looking at charts as just “lines” and start seeing them as an auction. Every time you place an order, it goes into the “Order Book” or the “Liquidity Pool.” For every buyer, there must be a seller. If you want to buy 1 lot of GBP/USD, your broker must find someone (usually a large bank or another trader) who is willing to sell 1 lot to you at that price. This is why price moves—when there are more people wanting to buy than there are people willing to sell, the price must rise to attract more sellers.
In 2026, most of this happens via “Electronic Communication Networks” (ECN) in milliseconds. Understanding this logic helps you realize why “slippage” happens during news events—if everyone wants to sell at the same time and there are no buyers, the price will “gap” down until it finds someone willing to take the other side of the trade. Market mechanics are simply the physics of supply and demand in action.
7. Stop Loss Mechanics
A Stop Loss is not just a button; it is your professional insurance policy. In the technical sense, a Stop Loss is a “Sell Stop” or “Buy Stop” order that sits on the broker’s server waiting to be triggered. Its sole purpose is to close your trade automatically if the market moves against you by a specific amount. At TryBuying, we consider trading without a Stop Loss to be the single biggest mistake a beginner can make. It is the difference between a controlled business expense (a small loss) and a catastrophic financial disaster.
When price hits your Stop Loss level, your order becomes a “Market Order,” meaning the broker will exit you at the next available price. In normal market conditions, this happens instantly at your exact price. However, during high volatility—like a sudden ZAR interest rate announcement—the price might jump over your level. This is why we advocate for wide enough stops to survive “market noise” while still protecting your core capital from a total wipeout.
↑ Back to Menu8. Take Profit Logic
While the Stop Loss protects your downside, the Take Profit (TP) order secures your upside. A Take Profit is a pending order that automatically closes your trade once a specific level of gain is reached. Many beginners make the mistake of “getting greedy” and moving their TP further away as the price approaches it, only to watch the market reverse and turn a winning trade into a loss. Professional trading is about sticking to the plan you made before the emotions of the live market took over.
Setting a logical Take Profit requires understanding “Structure.” You want to set your exit just *before* a major resistance level where sellers are likely to step in. By using a TP, you ensure that you capture your profits even if you are away from your screen or sleeping. Remember, a profit isn’t “real” until the trade is closed and the money is in your balance. The TP order is your tool for turning “pixels on a screen” into actual realized gains.
↑ Back to Menu9. Trailing Stops
A Trailing Stop is a dynamic version of a standard Stop Loss. Instead of staying at a fixed price, a Trailing Stop “follows” the market as it moves in your favor. If you are in a Buy trade and the price moves up 50 pips, a Trailing Stop will move up with it, maintaining a set distance. If the market then turns around and drops, the Stop Loss stays at its new, higher level, “locking in” a portion of your profits. It is a powerful tool for catching large trending moves while ensuring you don’t leave empty-handed if the trend ends abruptly.
However, Trailing Stops must be used with caution. If you set the trail too “tight” (too close to the current price), a minor pull-back in price will knock you out of the trade before the big move happens. At TryBuying, we suggest using Trailing Stops only once a trade has reached a 1:1 Risk-to-Reward ratio. This effectively creates a “Risk-Free” trade, allowing you to let your winners run without the fear of losing your initial investment.
↑ Back to Menu10. Swaps & Rollover
Forex is a “spot” market, but most traders hold positions for more than a day. Because currencies represent the economies of different countries, they each have different interest rates. A Swap (or Rollover) is the interest added to or deducted from your account for holding a position overnight (typically at 5 PM New York time). If you are buying a currency with a high interest rate (like the ZAR) against a currency with a low interest rate, you may actually get paid a small amount of “Positive Swap” every night you hold the trade.
Conversely, if you are on the “wrong” side of the interest rate differential, you will be charged a “Negative Swap.” While these amounts are usually small for day traders, they can add up significantly for “Swing Traders” who hold positions for weeks. It is also important to note that most brokers charge “Triple Swap” on Wednesday nights to account for the weekend. Understanding Swaps is vital for managing the long-term cost of your trades and avoiding “hidden” fees that eat into your profitability.
↑ Back to Menu11. Slippage & Gaps
In a perfect world, every trade would fill at the exact price you requested. In the real world, we deal with Slippage and Gaps. Slippage occurs when there is a delay between your order and the broker’s execution, or when there isn’t enough liquidity to fill your order at your requested price. This is common during high-impact news like the US Non-Farm Payroll (NFP). You might click “Buy” at 1.1000, but the broker fills you at 1.1005. That 5-pip difference is slippage.
Gaps are even more dramatic. They usually happen over the weekend when the market is closed but global news continues to happen. When the market re-opens on Sunday night, the price might “jump” or gap significantly higher or lower than Friday’s closing price. If the market gaps over your Stop Loss, your trade will be closed at the first available opening price, which could result in a larger loss than intended. This is why TryBuying advises caution when holding trades over the weekend, especially during periods of global political uncertainty.
↑ Back to Menu12. Margin Calls
The “Margin Call” is the final safety barrier between you and a negative balance. It is a notification from your broker that your account no longer has enough usable capital to keep your open trades running. If your losses continue and reach a specific “Stop Out” level (often 50% or 30% of your required margin), the broker’s system will automatically begin closing your trades—starting with the biggest loser—to prevent your account from going into debt. It is a brutal but necessary mechanism to protect both you and the broker.
Receiving a Margin Call is a sign of poor risk management. It usually happens when a trader uses too much leverage or refuses to use a Stop Loss. To avoid this, you must always monitor your “Margin Level Percentage” in your trading terminal. As long as this number remains high (well over 1000%), your account is healthy. If it starts dropping toward 100%, you are in the “Danger Zone.” At TryBuying, our goal is to ensure you never see a Margin Call by teaching you the mathematical discipline required to keep your capital safe.
