As in the front-office the multi-level analysis of the price action through the rainbow frequencies is a very valuable technique, so is a corresponding technique in the back-office of trading.
We may distinguish at least 4 complexity or organization levels:
1) The 1st simplest level is the single trade.
2) The second level is the complex hedge multi-trade. In other words a group of trades that are simultaneously open, probably opening successively after a pyramiding, till a final close of all of them.
3) The 3rd level is a consecutive sequence of hedge multi-trades that each goes immediately after the other till a final stop of opening hedge multi-trades. We may call it excursion.
4) The 4th level is a sequence of excursions, within a time interval. E.g. one day or one month.
If at each complexity-level, we impose risk management conditions the trading becomes really smooth, and of resilient succes
