Personally, I initiate an equally large order for all of these four currencies every day. I like to set the buying price 10% lower than that day's one day moving average. From my experience, this is a good way to get a buy order in at a local minimum. Once an order is filled, I create a sell order 10% above the buying price. This makes my portfolio increase by 10% every once in a while. Note that that the maximum average daily profit using this technique is 10% of your daily investment. If, in the future, the volatility decreases so that your orders rarely get filled, you can adjust the percentage with which your orders deviate from the daily moving average to be proportional with the standard deviation. For example, if we enter a period where the standard deviation is half of what it is now, we might choose to set our buy orders only 5% below the one day moving average and set the sell order 5% above that once it gets filled.
Disclaimer: It is not possible to predict the future. I do not take responsibility for your losses, regardless of whether they are caused by bad advice or wrongful statistics. Never invest more than you can afford to lose. Investing too much increases the chance of panic selling. These statistics are automatically generated as daytrading tools for myself, but I'm glad if others find them useful.
