coded this up in Pinescript - taking it as outlined in the book as its a very mechanical system. Wasnt very successful on most pairs.
Pinescript showed profits on
AUDUSD
EURJPY
EURUSD
GBPUSD
USDJPY
and it wasnt exactly spectacular but better than a savings account at the bank.
Maybe i didnt advise DeepSeek how to get the coding right (took a few efforts)
