// Firebird calculates a 10 day SMA and then shifts it up and down 2% to for a channel.
// For the calculation of this SMA either close (more trades) or H+L (safer trades) is used.
// When the price breaks a band a postion in the opposite of the current trend is taken.
// If the position goes against us we simply open an extra position to average.
// 50% of the trades last a day. 45% 2-6 days 5% longer or just fail.
