Crypto trading algorithm .. Machine learning (Scala/Java).

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 98% and above. The algorithm needs to predict both price and trend with time. 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 97% 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 atleast 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 Trend and price accuracy with time are very important Price is negotiable based on the produced algorithms. Willing to pay for performant algorithms See attached picture as an example
