SMA & EMA Simple Crossover

Tracks and highlights trends by using a simple SMA and EMA indicator. When a shorter SMA (default set to 10 periods) and a longer EMA (default set to 20 periods) cross over, a cross is placed upon the chart at the crossover point. Defaults settings for the periods and colours can be changed the user to meet their own preferences using the settings button (i.e. without having to edit the script).
