EUR/GBP : chart framework.

From a bullish trend (beginning in the end of the year 2016 and lasted until september, in the year 2018), the cross started a lateral trend. This is showed by the following chart where the uptrend is highlighted by the trendline and by the support lines and by the resistance lines (it means the main references : 0,83 and 0.93 ; 0.86 and 0.89).

We get the same view if we use a different time frame, for example a month. The monthly time frame shows the chart framework in a better way for the reason that it provides a general overview. 

We can notice the same references and then at now we can notice that the price is testing the resistance area at about 0.89. This price level is important because it represents also both the closing and the opening price of the previous green candle and of the previous red candle (see the circled area) : there was a price retracement and a volatility exhaust ; the green candle represented a long upper shadow candle ; in other words, at the end, the sellers prevailed over the buyers. 

The BB are emblematic, in this way : see the median line compared to the price and see the light blue lines compared to the price.

We have a confirmation of the trade change (bearish - bullish - lateral trend) also by the indications provided by MACD : we can notice the intersection of the yellow and red line (MACD and signal line) at the time of the overcoming of the zero line (see the light blue histograms), from the bottom upwards ; symmetrically, from the trend change bullish-lateral, from the top downwards.

Lastly, the EMA bundle shows the market direction : the following chart shows the slope of the EMA bundle where the trend is bullish and it shows the lack of slope of the EMA bundle where the trend is lateral ; then, the distance between the exponential moving averages is more marked for obvious reasons, in the uptrend (in this way, the EMA bundle provides a useful indication). 

The RSI shows the overbought and the oversold, in the levels of 70 and 30, respectively, as usual : the passageway through the two areas marks the change of trend in the chart, inevitably.
Of course, as I said previously, it needs to pay attention to the test of the resistance area at about 0.89.

"Average down" strategy : a path to disaster.

The strategy describes the process of buying additional shares at lower prices compared to the original purchase price. The aim is the following : it brings the average price that we've paid for all the shares down. It can be a discount but just apparently. In this way, in my opinion, that is the only reason that drives the investor to do it. 

It a somewhat obsolete technique and personally, I should not consider it a strategy. Against this background, it is just a state of mind and a mechanical process, without logic. 

Of course, the disadvantages are greater than the benefits. The reasons are the following :

• With repeated purchases of the same financial asset, we increase the risk of the portfolio : there is an excessive exposure of the portfolio, focused on the same stock. This is in contrast with a proper diversification principle ;

• The process involves the purchase of additional shares as the stock price goes down ; in this way, we are purchasing an asset for which the trend is bearish, clearly. A trader should follow the trend. We should increase the exposure with the uptrend and with strong fundamentals. At least, we should buy with clear reversal signals and respecting a logical investment plan ;

• At the end of the process, the investor obtained the following result : his portfolio is composed by a huge amount of shares of the same asset and if he reduced the loss (due to the lower average purchase price), on the other, his recovery rate (it means the percentage upside required to get the feed capital) is always higher in absolute terms than the current loss. This is especially true the more the final purchase price is lower than the original purchase price. In other words, the more the stock performance worsened. The following table explains the situation. 

          

We are assuming that the trend is bearish, of course. There are neither broker commissions nor financial fees, for simplicity. Then, the multiple purchases are of a same amount. 

With the multiple purchases, we bring the average price down, compared to the initial price and with regard to the situation without subsequent purchases. However, we can notice that the recovery rate is always higher than the loss percentage (in absolute value). Obviously, the gap is higher without subsequent purchases.

Nevertheless, it is reductive to focus on it : we should necessarily consider the higher exposure and risk. Then, with a proper investment plan, we should have cutted the losses and the purchase price at 0,50 EUR would have never exist (and the same for the lower prices). With the respect of the stop loss and of the target price, we really reduce the risk and we really build a proper trading strategy. 

The chart below shows what I said. Gain/loss % is better than Stock performance (equal to the gain/loss % without multiple purchases). Recovery rate (**) > Recovery rate (*). Recovery rate (**) > ABS (Stock performance) and Recovery rate (*) > ABS (Gain/loss %). 

Finally, I don't recommend the "average down" for the reasons above (apart from some exceptions, like change of trend or with other reversal signals). Instead, I highly recommend the respect of the risk management, of the SL&TP and in general of a suitable trading/investment plan.
