Hello, I have decided I want to learn coding and more specifically Solidity. However, I currently work in marketing and have 0 coding experience so far. Is there a specific course recommended? Do I need to learn specific languages before I learn Solidity, or can you make Solidity the first language you learn? Any advice or perhaps listed steps on what do first would be much appreciated

Hey @bluebullet02, hope you are ok and Welcome to our amazing community! 
Since you have zero experience in programming, you need to learn the fundamentals first.
Solidity is based on javascript syntax, so learning JS first will made easy to understand the solidity syntax and its extra features.
Try to follow the exact order that I have made the list.
1st Stage: Fundamentals.
- Ethereum Fundamentals Ethereum 101
- Crypto for Beginners
- Build a DEX Using JavaScript Programming for Beginners
2nd Stage: Solidity Programming Fundamentals.
- Build a Wallet On Ethereum Ethereum Smart Contract Programming 101
- Ethereum Smart Contract Security
- Build an NFT Marketplace Ethereum dApp Programming
3rd Stage: Solidity Programming Advance
- Build a DEX On Ethereum Ethereum Smart Contract Programming 201
- Program Oracles Using Chainlink Chainlink Programming 101
Extra Knowledge:
- Master DeFi in 2022
- Advanced DeFi DeFi 201 (Advance Solidity Programming Required)
See you around

I am also a beginner and need help in the following ---- trying to adjust the stochastic indicator and would like to adjust the code that is used as follows:
typical K% - k = ta.ema(ta.stoch(close, close, low, periodK), smoothK)
Would like to have the Close, High Close, Low Close as noted below
k = ta.ema(ta.stoch(close, high close, low close, periodK), smoothK)
Thanks in advance for your help
