Knowing the one day standard deviation of a currency may give a decent estimate of the day's lower and upper price bounds. For instance, if one wishes to buy at a local minimum, placing a buy order one or two standard deviations below the moving average has proven to be a decent entry point. Once the order fills, a sell order can be placed one or two standard deviations above the buy price, depending on one's risk tolerance or how quickly one wants to sell.
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.
