Dollar Cost Averaging (DCA) is actually a strategy used by stockmarket investors where they buy stock at fixed intervals even when the price is falling. So instead of just buying 1,000 stock at $10 per share on one day, they split the buying into different days.
On day one they can buy 10 shares, on day two they buy another 10 shares, on day three another 10 shares etc.
The idea behind this kind of buying is that on some days, the stock price would have fallen so the investor benefits from buying at a lower price.
In this strategy, I will apply the same DCA to trading currency pairs.
