FMN.sg and FHL.sg mirror FNMA and FMCC. How the correlation works is not clear, that is, the proximate, immediate causes.

For example, algo trading, which is being used by ARCA and ATDF, set parameters for buying, selling price sizing, timing and duration, percentages, agressive, less agressive accumulation, distribution, etc. This can lead to similar patterns in trading outcomes. Other factors can alter this such as competing algos and influx of trader types.
