Hi
Unfortunately unless I am mistaken, the darvas box code uses the DPO indicator (detrended price oscillator), and this DPO uses future data for past candlesticks. However it cannot achieve this for the most recent candlestick because using “future within historic of data” is one thing, but using “unknown future beyond present time” is another… This makes DPO (and therefore Darvas box) unsuitable for automated trading.
There is a second DPO calculation not using future data, but it gives very different results. Somebody wanted to try it on the french PRC forums, but we never heard back from him.
