Trading Strategy – Buy at Market on nth occurrence of Lower Low

  Hi Nicolas

  I would appreciate some guidance on coding a strategy that will buy at market on the nth occurrence of a Lower Low (LL). See picture attached for my expectaton of a Lower Low.

  In english i’m looking for somthing like this:

  Lower Low can be a variation of “low[5] > low[4] and low[4] >= low[3] and low[3] >= low[2] and low[2] < low[1] and low[1] < low[0]”

  Start with setting the variables LL1 to LL5  to 0

  Next

  1st occurence of a LL set LL1 = Price of Low[2] within the Lower Low

  In between each lower lower there will be a Lower High (which could be the opposite of the description of the Lower Lower above).

  2nd occurence of LL set LL2 = Price of  Low[2] within the 2nd Lower Low

  3rd occurence of LL set variable LL3 = Price of  Low[2] within the 3rd Lower Low

  Then buy when LL3 is <> 0

  Then when on market set LL variables back to 0 and start again.

  Thanks for our support in advance.

  Steve

  Hello,
  The signal is clearly in the style of Williams’ fractals.
  To keep track of previous signals, I believe you can play with intermediate variables, and a table to log LL values. Something like this (not tested):
  Remark: not sure why there is a need for 5 variables and why LL3 should be initialized if it is set to 0 just after

  Store LL values

  once HHcount = 0 once LLcount = 0 cLL = ... // Put here the conditions for LL cHH = ... // Put here opposite conditions for HH IF cHH and HHcount=0 THEN // Detect a swing high as intermediate signal HHcount=HHcount+1 ENDIF IF cLL and HHcount>0 and LLcount<2 THEN // Initialize the first 2 variables when there is a swing low LL[LLcount]=low[2] LLcount=LLcount+1 HHcount=0 ENDIF IF cLL and HHcount>0 and LLcount=2 THEN // Action on third swing low BUY xxx // Put here BUY instructions LLcount=0 HHcount=0 ENDIF

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

  once HHcount = 0 once LLcount = 0   cLL = ... // Put here the conditions for LL cHH = ... // Put here opposite conditions for HH   IF cHH and HHcount=0 THEN // Detect a swing high as intermediate signal HHcount=HHcount+1 ENDIF   IF cLL and HHcount>0 and LLcount<2 THEN // Initialize the first 2 variables when there is a swing low LL[LLcount]=low[2] LLcount=LLcount+1 HHcount=0 ENDIF   IF cLL and HHcount>0 and LLcount=2 THEN // Action on third swing low BUY xxx // Put here BUY instructions LLcount=0 HHcount=0 ENDIF

  PS: when do you plan to sell?

  Thanks for the quick response!

  I’ll see if i can incorporate this into my strategy! I’m still playing around with a trailing stop strategy for Selling.

  It doesn’t like this, do i need to declare this as an array somehow prior to storing the values?

  LL[LLcount]=low[2]

  Hello,
  Never used arrays before, but looking at one fresh post from @Nicolas, there is a need of $ sign
  $LL[LLcount]=low[2]
  To be tested

  Indeed, you have to put a $ before a variable name to be considered as an array.

  You getting anywhere with this s_darbey  ?

  I am watching with interest as I would love to see code that stores HH / HL and which flags up a change to LH / LL (and vice versa).
