Recency bias is an explanation of how we are affected by more recent events than events that occurred further in the past. They dictate our decision-making because of an expectation that the immediate future is likely to be the same as the events that have just occurred.
So an event that occurred one or two hours ago is likely to have a greater impact on our mindset than an event that occurred a week ago.
While this tends to have a minimal impact on normal daily life, this phenomenon interferes with a trader’s ability to follow a strategy – especially after experiencing a temporary performance downturn or drawdown.
Traders are likely to focus on recent losers
To illustrate, consider an example where a trader has taken 40 trades overall and the first 30 trades were all winners. After these initial 30 winning trades, the trader would feel very positive and confident, and would have no hesitation taking more trades. If, however, the following 10 trades all lose, then these will have a greater impact on the trader’s mindset and may cause the trader to lose confidence, because they were the most recent set of events to occur.
The emotional impact on the trader from the losing trades is much more potent, because they are more recent, despite the fact that the system has produced 30 winning trades out of 40. The trader’s mind is using only the most recent data to form an emotional state.
This continues to influence the trader in two ways: Firstly, this negative state of mind leaves the trader vulnerable to mistakes and secondly, the trader may question the strategy itself.
This can lead to two common symptoms of switching and fear of taking trades.
Switching is the continuous changing between trading strategies, without an actual basis for doing so. This usually happens after either experiencing a sequence of losing trades or when the account goes into negative equity.
The most recent losing trades are convincing enough to make the trader believe that the strategy is no longer viable, despite the fact that the strategy is profitable overall.
When this happens, the trader switches to a different strategy. When a similar performance downturn occurs using the new strategy, the trader switches again and so on.
In the trader’s mindset, they are successfully avoiding losing streaks because they stop trading the strategy once it becomes unprofitable. In reality, the profitable periods of the system are never experienced because each system is never fully traded through the drawdown period and back into profit; only the losing streaks end up impacting the trading account.
If the strategy has been tested and there is evidence that it is a winning strategy, then the correct course of action would be to trade through the drawdown period. However, the poor trading results are the most recent event to occur and so instead of following a logical plan, they try to avoid losing trades and in doing so, switch from a winning system.
Fear of the next trade
Another common symptom resulting from recency bias is a fear of taking further losses. The fear instilled from the recent losing trades influence the trader to the extent that they find it difficult to pull the trigger and execute the next trade.
The trader then tries to pick winning trades based on gut instinct or emotional judgement and veers away from trading in accordance to the rules of the strategy. They 'feel' that the trade will not work out and so they do not take that trade. More often than not, this results in winning trades being missed and so the trading account never has a chance to recover from the drawdown.
The correct course of action is to trade through the drawdown periods and back into profitability. However recency bias is hindering the trader’s ability to execute individual trades according to the system.
Get into a logical state of mind using a trading journal
Recency bias results in the trader making decisions based on emotion and not on logic.
Once the mind is in an emotional state, it is difficult to switch the mindset back to a logical state.
The use of a trading journal can help get the mind thinking in a logical way because a trading journal presents facts and data. Assuming that a trader always records their trading activity, when a trader is looking at the results of past trades, they are taking in information that is derived from facts and not emotion.
This data cannot be disputed, and reading over previous results that show a system is profitable, will bring the mindset back into a logical state.
Negating recency bias
This counteracts the effects of recency bias because the recent losing trades are no longer the dominant factor influencing the trader. In our example, the results of the 30 winning trades would be more influential than the most recent 10 losing trades, because the trader is observing the system as a whole.
This reduces the likelihood that a trader will succumb to switching or fear of taking the next trade, because the results will show that statistically if they keep trading, they will end up with a profit.
So far, you have learned that:
- Recency bias explains how we are affected by the most recent events that occur.
- They dictate our behaviour because we shape our expectation of the immediate future based on the immediate past.
- In the scenario of a trader having 30 wining trades followed by 10 losing trades, the trader is more likely to focus on the 10 losing trades, because they are the most recent event to occur.
- This can lead to switching and fear of taking the next trade.
- Switching is where a trader will switch strategies every time a strategy enters into a downturn. This results in a strategy not being traded back to profitability.
- Fear of taking the next trade leads to a trader trying to avoid losses and attempting to stay away from losing trades.
- They miss trades based on gut feeling and ultimately miss the winning trades as well, leading to a less profitable strategy.
- In order to combat recency bias, a trading journal can be applied. Looking at the results of a trading journal helps because this shows the strategy results as a whole and a trader will not focus on just the most recent losing trades.
