Module trades/getFamilyMaps

default

• default(trades: TradeRecords): FamilyMaps

• Group all trades into what is called a "family" keyed by sl. In other words all trades with the same stop loss belong to the same family.

  Example, the following nine (9) orders:

  1. Order 314327066 314307379 314327066 BUY GOLD @ 1782.07 SL 1765 TP 1797
  2. Order 314327067 314307378 314327067 BUY GOLD @ 1782.07 SL 1765 TP 1792
  3. Order 314327068 314307377 314327068 BUY GOLD @ 1782.07 SL 1765 TP 1789
  4. Order 314327069 314307375 314327069 BUY GOLD @ 1782.07 SL 1765 TP 1786
  5. Order 314327070 314307374 314327070 BUY GOLD @ 1782.07 SL 1765 TP 1784
  6. Order 314391975 314391975 314391975 SELL_STOP ETHEREUM @ 4200 SL 4800 TP 4140
  7. Order 314391976 314391976 314391976 SELL_STOP ETHEREUM @ 4200 SL 4800 TP 4100
  8. Order 314391977 314391977 314391977 SELL_STOP ETHEREUM @ 4200 SL 4800 TP 4150
  9. Order 314391978 314391978 314391978 SELL_STOP ETHEREUM @ 4200 SL 4800 TP 4160

  This functionality might be better served by grouping on the position field or even the customComment field but unfortunately these fields are unreliable.

    Map(2) { 1765 => [ 'BUY' ], 4800 => [ 'SELL_STOP' ] },
    Map(2) { 1765 => [ 'GOLD' ], 4800 => [ 'ETHEREUM' ] }
