// Revision:        1
// Author:          @JayRogers
//
// Description:
//  - Strategy based around Open-Close Crossovers.
// Setup:
//  - I have generally found that setting the strategy resolution to 3-4x that of the chart you are viewing
//    tends to yield the best results, regardless of which MA option you may choose (if any)
//  - Don't aim for perfection. Just aim to get a reasonably snug fit with the O-C band, with good runs of
//    green and red.
//  - Option to either use basic open and close series data, or pick your poison with a wide array of MA types.
//  - Optional trailing stop for damage mitigation if desired (can be toggled on/off)
//  - Positions get taken automagically following a crossover - which is why it's better to set the resolution
//    of the script greater than that of your chart, so that the trades get taken sooner rather than later.
//  - If you make use of the trailing stops, be sure to take your time tweaking the values. Cutting it too fine
//    will cost you profits but keep you safer, while letting them loose could lead to more drawdown than you
//    can handle.
