Crypto Trading — Machine Learning (Scala/Java) developer

Need a Scala/Java developer with ML knowledge to create a trading algorithm that used to buy and sell on various time frames. Accuracy needed is 90% and above. The algorithm need to be preferment for low and high time frames and well back-tested. The main goal is to catch every price bounce with buy and sell signals. This is mainly for Crypto trading and only interested in long signals

I am looking for an algorithm they predicts buy and sell on various time frames (1m,5, 10m, 15m, …, etc) with a minimum of 90% accuracy if not higher.
The algorithm need to be preferment for low and high time frames and well back-tested. The main goal is to catch every price bounce with buy and sell signals.
only interested in long signals
The algorithm focuses on Cypto market only
The algorithm needs to be tested with 2 different coins (excepts BTC)
– Back test for various time frames
– Live test/trades
– Dashboard for both backtest and live trades to show me how the algo is performing
Price is negotiable based on the produced algorithms. Willing to pay for performant algorithms

See attached picture as an example
