The 4h chart gave me a small profit (considering going fiat when a bearish crossover occured-and not going short on bitfinex)
Whereas the 1h chart gave me huge profit. I did this backtesting from september til january.
At that time, I didn't know anything about margin trading. Considering these new options (leverage+possibility of shorting), it was obvious that you could be a winner by just following MACD 1h crossovers. You can ofcourse have a better strategy if you add other indicators and add fundamental analysis to your strategy.
I'd like to add that considering the fluctuations of bitcoin, especially during bubbles (like in April or November), using MACD in such big timeframes is quite irrelevant. I didn't try to go in 15m timeframe because I think you will get eaten by fees and swaps. Finally, you will get more often wrong than right, but you winnings will be much more important and erase your losses.
Hope I did help
Any indicator/bot under the sun would give you a profit in that period. It was period of huge bubble, then huge crashes. Just go to cryptotrader.com and backtest any bot you find there for that period and it will be big winnings.
It's long flat markets where the value of indicators comes to shine.
