indicator = MACD
pattern = diamond pattern on indicator (already backtest can be used on this indicator)
function to predict if there reversal pattern or not
note: diamond pattern = low volatility sideway until the break out, after the breakout the volatility will increase
WARNING: if break downside under 1817 possible hit 1770, careful!!!
extranote: I don't think under 1828 would be good as bullish signal, under 1828 can ruine the trendline for bull flag and bullish channel
even if there reversal on 1817 should be seen as bearish signal until invalidate
