// TRIX chart and timing signal

// You can use this to display the graph or change the parameter to show it as a buy/sell signal (default)
// Changing the parameters allows you to use it for different timing periods and TRIX 25/8 is very close to Mercury.
// Be careful to NOT name it TRIX or it may overlay ABs canned version.
