Also, note that in Greek, we often use the English terms for "Bollinger Band" and "moving averages" but can also translate. The instruction says "use appropriate Greek terminology for crypto/tech terms" but also "keep proper nouns in original form". "Bollinger Band" is a proper noun (named after John Bollinger), so we keep it as "Bollinger Band" or "ζώνη Bollinger"? The instruction says "keep proper nouns (names, company names) in original form". "Bollinger" is a name, so we should keep "Bollinger Band" as is, but we can add the Greek translation in parentheses? The example in the original article uses "Bollinger Band" in English. I think it's fine to keep it as "Bollinger Band" in Greek text, but we can also use "ζώνη Bollinger" which is common. To be safe, I'll use "ζώνη Bollinger (Bollinger Band)" in the first occurrence, then just "ζώνη Bollinger" later? But the instruction says "keep proper nouns in original form", so I'll keep "Bollinger Band" as is. However, in Greek, it's common to say "Bollinger Band" without translation. I'll use "Bollinger Band" throughout.
Similarly, "moving averages"
