My strategy is to get profit, of course I will buy at low prices and take the opportunity as best as possible so that I will have the opportunity to get profit when prices go up, then I will save some and some of it I use to buy again
but the problem is sometimes the price in the market confuses you. the rising price is not necessarily the highest price, and the declining price is not necessarily the lowest price. you might make a mistake in sell and buy, thats why the strategy is needed to allocate how much money to buy in that time and another time, just in case if not in line with expectations..
