//200 dma
//1 signal per month - trade only at 'end of month' to cut whipsawing in and out. 'End of Month' is whatever trading day is 
// nearest to the default day 28 of month in pinescript - there is no easy method to obtain trading end of month date.
// Day 28 is default so not to miss Feburary. 
//If > 200DMA enter long
//If < 200DMA goto cash
// Important Steve Burns used SPY TOTAL RETURN INDEX used not just SPY Price. Please use the ADJ at bottom of chart in Trading View. 
// 3 Jan 2000 to 28 Jun 2021 - https://www.newtraderu.com/2021/06/30/200-day-moving-average-vs-buy-and-hold/
//Steve Burns Results : 585.8% return on SPY vs 365% buy and hold with 12 trades
// My Results :         415% return (on SPY with ADJ) vs BUY and HOLD of 318.9% in 12 trades so not perfect
