Reproducing `units=5` would mean feeding a fraction derived from an equity curve that does not exist until the run is over. Indicator: `raptorbt.ema` seeds on a simple mean of the first `period` bars and emits from bar `period-1`, while manifoldbt seeds on the first observation and emits from bar 0 (measured: 11 leading NaN for span 12, and ema[11] equal to sma(12)[11] to the last bit). The two are the same recursion with a different warmup, so the signal differs early and the round-trip count with it. Its `sma` and `rsi` do match, which is why the other three workloads run."

Reproducing `units=5` would mean feeding a fraction derived from an equity curve that does not exist until the run is over. Indicator: `raptorbt.ema` seeds on a simple mean of the first `period` bars and emits from bar `period-1`, while manifoldbt seeds on the first observation and emits from bar 0 (measured: 11 leading NaN for span 12, and ema[11] equal to sma(12)[11] to the last bit). The two are the same recursion with a different warmup, so the signal differs early and the round-trip count with it. Its `sma` and `rsi` do match, which is why the other three workloads run."
