Overview Of Day Trading
Day trading the Forex markets is a popular trading technique that involves buying and selling currency pairs within a single trading day. The goal of day trading is to make a profit by taking advantage of small price movements in the market and trading will usually be completed using smaller time frame chart such as 30min and 1hr.
Day trading will require a well written trading strategy that dictates which market conditions must be met prior to entering a trade. This assists with being able to react quickly and enter a trading position at the optimal entry point. The individual trader must trade with discipline to ensure that the strategy is implemented correctly.
The criteria set out in the trading strategy will depend entirely on the individual. Some traders will rely solely on technical analysis and patiently wait until the trading signals are met, reacting immediately on a technical indicator providing the required signal. Others will depend more heavily on fundamental analysis and trade the volatility that follows an economic announcement.
Whichever method of identifying a trading opportunity is used, the common element is that trades are held for a short amount of time and never being held overnight. Once the required pip gains have been reached, the trade is closed with no thought of holding onto the position. The desired outcome is to accumulate a large number of small gains.
Due to the size of gains being relatively small, traders will often utilise leverage to maximise their trading position and create value from small pip gains.

What Is The RSI Indicator
The RSI is designed to provide an indication of momentum in the market place by measuring speed and change of price movements to provide the user with over or under valued price of a chosen currency pair. It is a simple oscillator that can provide useful information that assists a trader in pinpointing an entry point for a trading position, and just as importantly, a signal to exit the trade.
The RSI indicator is generally set to provide an overbought signal if the reading is above 70 and an oversold signal if the reading is below 30. These parameters can easily be tailored by the user to suit individual risk appetite. The overbought signal could be set to 80, providing more certainty that the currency is overbought. Equally the oversold signal could be reduced to 20.
Adjusting the parameters to more conservative levels may provide more certainty on forthcoming price movements, but it will reduce trading opportunities.
The above EUR/USD technical chart demonstrates how the RSI indicator oscillates between overbought and oversold. The first overbought reading coincides with the end of a bullish trend in price movement. Following the overbought signal, prices revert in a downward direction as traders are exiting long positions in favour of short.
The end of the bear move is reflected by the RSI showing an oversold signal, this is followed by a strong bull move as traders take long positions.
The above chart is a clear demonstration how the RSI indicator can be used to understand momentum and enter trades early in anticipation of a reversal. It is also useful to gain an insight into when is a good time to exit a trade and take potential gains prior to a reversal materialising.
Day Trading Strategies
The Relative Strength Index (RSI) indicator is a powerful tool that can help you analyse market trends and make informed decisions about when and how to buy or sell. Below we will discuss a couple of the most popular RSI day trading strategies, these are trend trading and range trading, using over the overbought and oversold signals provided by the indicator.
RSI Trend Trading
Trend trading is a style that can be incorporated into a day trading strategy, particularly those that are written to be more risk adverse. Identifying the current price trend is a popular form of analysis for traders, as understanding price movement and momentum will go a long way to reducing potential risk and creating higher probability trading.

Information provided by the RSI can be used to identify potential reversals or continuations in the market trend. When using RSI trends for day trading, traders typically look for oversold or overbought conditions within an existing uptrend or downtrend, respectively. By following this approach, traders can enter trades with high probabilities of success while minimizing their risk exposure.
Let's assume that a strong downtrend is currently underway and it looks to continue for some time, traders will be looking to take short positions. To pin point a precise entry point, traders will look to take a position once the RSI indicator is showing an overbought reading and prices are near to the trend line.
Prior to using the Relative Strength Index to make trading decisions, it is important to identify the current trend as the indicator settings may require adjusting. The settings are usually pre-set to indicate and overbought signal at 70 and oversold at 30.
During a strong trend as shown on the above EUR/USD 1hour chart, it may be more probable that overbought occurs at a reading of 50. To determine this it would be wise to plot a line on the RSI across the peaks of the indicator during the trend in question.
Range Trading
The RSI indicator can also provide extremely useful information when trading within a range. A range can be identified by looking at historical prices and plotting strong levels of support and resistance. At these significant price points, momentum often shifts and bounces of support and heads to resistance and visa versa.

As prices approach a key point of lets say resistance, traders will look to close any long positions they may hold and enter a short. The RSI indicator helps to identify when momentum is weakening and as an overbought signal is generated, this will be taken as the point to action sell in the expectation of prices reverting to support.
Limitations Of RSI Indicator
The RSI indicator is a measure of momentum and is not to be taken as a guarantee of signal of a price reversal. It is important to remember that although and overbought reading may be in play, it does not necessarily mean that buying pressure won't continue. An overbought or oversold signal can span many time frames, it is therefore important that a trading position is protected by placing a stop loss order in line with risk to rewards ratio's set out in your trading strategy.

Protecting Your Position
When using the RSI indicator, it is crucial to protect your trading position. This can be done in several ways, such as setting stop-loss orders or trailing stops to minimize potential losses. If a long position is being taken, setting a stop loss order close to underneath the previously plotted trend line would be sensible. If prices break the trend and begin to revert downwards, your position will be automatically closed without incurring substantial losses.
Another way is to avoid entering trades solely based on RSI signals and instead confirm them with other technical indicators or fundamental analysis.
It is also important to stay disciplined and stick to your trading plan, avoiding emotional decisions that could jeopardize your position. Additionally, regularly monitoring market conditions and adjusting your strategy accordingly can help protect your position from unexpected changes in trend direction or volatility spikes. By implementing these measures, traders can safeguard their investments and maximize their chances of success when utilizing the RSI indicator for trading purposes.
Summary

Traders use this indicator as an oscillator, meaning it fluctuates between 0 and 100 to signal whether a currency pair is overbought or oversold. When the RSI reaches above 70%, it indicates that the currency pair may be overbought and due for a pullback, while readings below 30% suggest that it may be oversold and ready for a rebound.
