Trading may seem overwhelming to the average person due to the complex nature of the financial world and the fast-paced environment of the trading floor. There has long been a common misconception that it requires years of experience and an innate talent for market analysis to be a trader. However, seasoned traders often describe their profession as one that demands resilience and an appetite for uncertainty.

Yet, behind the scenes, there are many untold stories – some amusing, others devastating, yet they are worth sharing and each with its own valuable lesson. These are the true stories experienced by the authors themselves.

Professionally managed by property managers and guided by dedicated REIT managers, these trusts ensure optimal occupancy and income generation. REITs are also liquid, transparent, and diversified, offering exposure to multiple properties across different locations.

In Singapore, REITs have become a cornerstone of many investment portfolios due to their ability to generate consistent dividend yields, often higher than traditional stocks or bonds. However, choosing the right REIT requires understanding specific financial ratios and metrics. This article highlights the key aspects and ratios beginners should evaluate before investing in Singapore REITs.

The first story took place at a trading simulation competition held on the trading floor, where every second mattered. Among the participants was a trader tasked with executing orders from a fund manager, who gave clear instructions to buy 100,000 shares. However, in a moment of haste, she mistyped the order with an extra zero. Instead of buying 100,000 shares, she bought 1,000,000 shares. By the time she realised her mistake, it was too late! She panicked and hurriedly tried to retract the order, but then the large order was filled. She thought to herself, how could I have made such a rookie mistake?

This kind of order entry error is well known within the trading community as a fat-finger error. The term “fat-finger” is a symbolic meaning that a trader unintentionally pressed the wrong keys and made erroneous orders. The fat-finger error the participant made sent a shockwave through the simulated market, causing the stock price to surge, leading to an overvaluation. This prompted the other traders to react and capitalise on the inflated price by selling off their holdings. Consequently, her portfolio became heavily weighted with overvalued shares. Eventually the stock’s price corrected itself, resulting in a significant unrealised loss for the portfolio amounting to US$5.5 million.

Some examples of S-REITs include Mapletree Pan Asia Commercial Trust (which owns Vivo City) and CapitaLand Integrated Commercial Trust (which has a stake in ).

A trader can avoid making fat-finger errors by checking the order before submitting. It can be helpful to go through the entire order details one by one; one may choose to read it aloud to themselves to ensure the order is correct. Traders who tend to be hastier could also remove one-click trading functions; this is an additional step where the order summary is previewed before submission. Any correction can still be made at this stage.

However, despite this measure, human errors can still happen.  What separates a good trader from a great one is the ability to react quickly and minimise losses, even in the face of unexpected errors.

The second story highlights how traders handle mistakes. One night, a trader was tasked to clear some positions with several counterparts. The previous trader had been rotated due to mistakenly mixing up the volume for forex with metals resulting in an unintended large order for metals. Before he began his shift, he was explicitly warned not to make the same mistake.

However, upon entering the volume and submitting the order, he gasped in horror when he realised the previously incorrect trade volume had not been adjusted, and he `had unknowingly submitted the incorrect order again, repeating the same costly mistake. The trader had just taken on a US$250 million position. Each dollar change in the price of gold would have resulted in a US$100,000 loss. To make matters worse, the market began moving against him.

Instead of panicking, the trader kept his composure and assessed the situation. He made a swift and decisive decision—breaking the position into smaller orders to rectify the mistake. As a result, the loss was limited to US$50,000. In a similar situation, the outcome would likely have been far worse if another trade had panicked.

While double-checking orders can systematically reduce errors, mistakes can still happen. When they do, traders must:

• • stay calm – Panic clouds judgement and leads to poor decision-making
  • take control of the situation – Accept the mistake and act decisively
  • think rationally – A clear mind helps to navigate the best course of action

Another common behaviour that can be observed after a trader makes a mistake is holding onto the erroneous trade, hoping to break even or recover losses. This creates more pressure on the trader, resulting in a spiral and worsening the mistake. A trader must know that they will not always get away with it. The best course of action is to stick to the plan, take responsibility, and move forward.

The third story shares a common situation faced by traders when they hold a position. Early in a trader’s trading journey, the trader found themself in a situation where he had heavily bought into a promising stock. He had purchased the stock at US$15, convinced that it would skyrocket based on his analysis. The stock indeed rose to US$25 over the first few months, but the trader did not secure his profits as planned, confidently thinking that there was more room for the stock price to appreciate.

As the months passed, the stock’s price began to decline below the entry point. The trader convinced himself that the stock would rebound and believed he just needed to be more patient. Eventually, the stock price fell to around US$7, half of the entry price. The decision of not cutting losses had a huge impact on the trader’s confidence.

He learned that cutting losses quickly isn’t just about limiting financial damage, but about having a disciplined, systematic approach to trading—often referred to as the “stick to the plan” mindset. The easiest method is to keep a trading journal. It is better to have the entry and exit clearly stated. Other personal notes can be jotted down; the reasoning for taking on a position, the psychology of the trader during the holding period, or even ongoing news that may have affected the analysis. Making notes allows the trader to revise and recondition his behaviour. The trade journal is also a stronger form of commitment psychologically for a trader.

These stories have shown that trading is filled with challenges and complexities that even experienced traders are not immune to mistakes. Mistakes such as fat-finger error or repeated miss-entries can lead to significant financial consequences. However, they provide valuable lessons; the importance of paying attention to detail and staying calm under pressure. Maintaining a trading journal and having a well thought-out trading plan can help traders to avoid making emotional decisions and improve their strategy.  All these boils down to the continuous learning from past mistakes and building the ability to adapt to the fast-moving financial market. Traders can turn their experiences, both good and bad—into valuable insights that shape their future success.
