If you get a weekly candle close above the EMA web, go long. Place your stop at the low of that candle close. Reverse your position to SHORT if that price reverses and breaks the LOW of that candle. If there is to be another BTC bull train you will be on it, if not you will be able to get the catch the bear train back home too.
My chart arrows show the FIRST weekly candle close above the EMA web.
