Please I need help to draw trend lines that will:
1. Draw two trend lines high and low
2. The trend lines will use 2 anchor point.
1st point will start from 0 to 48 previous candle
2nd point will start from 0 to 24 previous cable
3. These lines will only be drown once at 00:01
4. At 23:59 these lines will be deleted
5. While the line is drown..if price goes above or below it should alert price is below or above trend lines.
 

  1. Help you with what? You haven't stated a problem, you stated a vague, incomprehensible want. Show us your attempt (using the CODE button) and state the nature of your difficulty.

    We're not going to code it for you (although it could happen if you are lucky or the issue is interesting).

  2. Until you can state your requirements in concrete terms, it can not be coded.

  3. “1st point from 0…48” is meaningless. A coordinate has a single price and time. You just implied 196 prices and 49 times. See № 2.

  4. “2nd point from 0…24” means first and second could be the same.

  5. Why are you including index zero, when you want to draw at the start of a new day?

  6. There is no water here, you can't drown.
