// 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.

//----------------------- TO DO LIST
// 1st days profit target is the 30 pip line *not* 30 pips below average as usually. -----> Day()
// Trailing stop -> trailing or S/R or pivot target
// Realistic stop loss
// Avoid overly big positions
// EUR/USD  30 pips / use same value as CurrentPipStep
// GBP/CHF  50 pips / use same value as CurrentPipStep 
// USD/CAD  35 pips / use same value as CurrentPipStep 

//----------------------- OBSERVATIONS
// GBPUSD not suited for this system due to not reversing exhaustions. Maybe use other types of MA
// EURGBP often sharp reversals-> good for trailing stops?
// EURJPY deep pockets needed.
