//This script has been created to take into account how the following variables impact trend for SPY 1 Minute
//The SPY stop losses/take profit have been set at 30 cents which equates to 15 cents on SPY 1 DTE ATM contracts
//5 ema vs 13 ema : A cross establishes start of trend
//MACD (Line, Signal & Slope) : If you have momentum
//ADX : if you are trending
//RSI : If the trend has strength
//The above has been optimized to determine pivot points in the trend using key values for these 6 indicators
//bounce up = ema5 > ema13 and macdLine < .5 and adx > 20 and macdSlope > 0 and signalLine > -.1 and rsiSignal > 40
//bounce down = ema5 < ema13 and macdLine > -.5 and adx > 20 and signalLine < 0 and macdSlope < 0 and rsiSignal < 60
//White L's indicate that 5 of 6 conditions are met due to impending uptrend w/ missing one in green below it
//Yellow L's indicate that 6 of 6 conditions still are met
//White S's indicate that 5 of 6 conditions are met due to impending downtrend w/ missing condition in red above it
//Yellow S's indicate that 6 of 6 conditions still are met
//After a downtrend or uptrend is established, once it closes it can't repeat for 10 minutes
//Won't open any trades on last two minutes of any hours to avoid volatility
//Will close any open trades going into last minute of hour
