Long trade for OIL

When OIL moved above MA100 it was a signal that down trend was over and we should use trading systems based on flat market conditions. There was a good SELL signal when price bounced from UP Bollinger Band. Who opened the short positions, now they have profit. What about new potential signal? It could be BUY signal, when price touch MA50. If price bounce and MACD (H) and DMI confirm the reversal, we'll have good oppotunity to enter the new up trend in the start point. But now we do nothing - it's also a position when you work in the financial markets.
