it is not good
1. Salam;
2. it’s very good. thanks.
3. why didn’t you use switch-case instead of those else-ifs?
4. also it was better to use pattern names without numbers as the parameter.
5. another suggestion of mine is to use more details for those patterns which produce very buy/sell signals (to decrease signals and to produce more precise signals)
6. the final suggestion is to combine very powerful patterns and making it the default param
7. thanks again for your wonderful work.
It seems that the formula references FUTURE quotes.
