//The purpose of this script is to spot 1 hour pivots that indicate ~5 to 6 trading day swings.
//Results indicate that swings are held approximately 5 to 6 trading days on average, over the last 6 years.
//This indicator spots a go long opportunity when the 5 ema crosses the 13 ema on the 1 hour along with the RSI > 50.
//It also spots uses a couple different means to determine when to exit the trade. Sell condition is 
//primarily when the 13 ema crosses the 5 ema and the MACD line crosses below the signal line and
//the smoothed Stoichastic appears oversold (greater than 60). Stop Losses and Take Profits are configurable
//in Inputs along with ability to include short trades plus other MACD and Stoichastic settings.
//If a stop loss is encountered the trade will close. Also once twice the expected move is encountered
//partial profits will taken and stop losses and take profits will be re-established based on most recent close
//Once long trades are exited, short trades will be initiated if recent conditions appeared oversold and
//input option for short trading is enabled. If trying to use this for something other than SPXL it is best
//to update stop losses and take profit percentages and check backtest results to ensure proper levels have
//been selected and the script gives satisfactory results.
