// Seems like this strategy works better if we reverse the EMA filter logic.
// "Description: This basic scalping strategy allows you to enter the market based upon sentiment
// provided by the EMA, set at 255 periods. When price is trading below the 255 EMA, you would
// look to enter a LONG BUY positions, and when price is trading above the 255 EMA, you would
// look to enter a SELL SHORT position. The MACD lagging indicator will show you clear signals for
// when to do this. When the MACD lines cross in a bullish manner and price is below the 255
// EMA, buy. When the MACD lines cross in a bearish manner and price is above the 255 EMA,
// sell.
// NOTE: Make sure that price is trading away from the 255EMA before entering a LONG or SHORT
// position. As you can see in the chart below, the clearest signs for trade entry were presented
// when price was trading AWAY from the 255EMA"
