EMA50Diff & MACD Strategy

One of my attempts to create a strategy for BTC.

Its a combination of EMA50Diff (the difference between spot and EMA50) and MACD.
Buy signal if (EMA50Diff) < -(EMADiffThreshold),
(MACD bearish crossunder),
(MACD) < -(MACDThreshold),
(EMA50Diff) > (EMA50Diff 1 candle ago),
(EMA50Diff 1 candle ago) < (EMA50Diff 2 candles ago)

Sell signal if (EMA50Diff) > (EMADiffThreshold),
(MACD bullish crossover),
(MACD) > (MACDThreshold),
(EMA50Diff) < (EMA50Diff 1 candle ago),
(EMA50Diff 1 candle ago) > (EMA50Diff 2 candles ago)

Exit either when target or stoploss get reached.

Initial capital is set to 100k and its currently going all-in on every trade but im looking for a better way to handle position sizes already..
Also i included slippage of 30 ticks and exchange commission of 0.15% (e.g. 2x BitMEX market taker fee)

Works best on 15m on bitfinex, bitstamp and gdax and i'm still trying to optimize it for bitmex too, will update when i got there..
