This tutorial covers all the prompts and code used in the video tutorial for this ChatGPT MT5 EA. This is purely educational so be sure to learn, adapt and test the code before use. Many traders use EA’s to trade on CFD prop firm via a VPS which allows the EA to run 24/7 without your computer having to be on all day.
Prompt 1
Upload MQL5.pdf
Please read this entire mql5 pdf, master the concepts of coding in mql5 along with financial markets, risk management and trading strategies. You will write in mql5 to create expert advisors in this chat for the mt5 platform. Make the code professional and efficient, considering system resources when the code is running, given execution speed is critical. Please wait for directions as to the code I need you to write. For now, simply take in the mql5 knowledge to ensure you can write code at expert level.
Prompt 2
Please make an EA that buys the US30 symbol at the market open time (16:30) and looks for additional entry points when the market pulls back by its average true range for the day. It will build a position over time, bringing stops to break even once the current price is 1.5 times away from the current daily ATR. It will close all trades at a target balance that I input. Stops to be 1.2 of the ATR lower than the entry price. Ensure that we only move the stops to break even once per trade, we can have multiple trades running for this strategy but don’t allow it to send more than one trade at a time. Additionally, with consideration for prop firms, I would like there to be a failsafe stop, closing out all trades if the equity reduces by a percentage I input.
Prompt 3
After compiling the code, copy all of the errors (click the top one, then hold shift and click the bottom one and then CTRL C to copy). Then paste those errors directly into the ChatGPT chat.
Prompt 4
After compiling the next set of code, copy all of the errors (click the top one, then hold shift and click the bottom one and then CTRL C to copy). Then paste those errors directly into the ChatGPT chat.
Prompt 5
The same errors are still present. **Accidentally pasted the code in.
Prompt 6
Paste the errors in again
Prompt 7
Errors again
Write the full EA but please ensure there are no errors.
Prompt 8
still errors. ensure all the mqql5 is up to date please, maybe the refference pdf i gave you is a bit old
Prompt 9
These i’s are giving us some serious trouble, why is it an error and why aren’t you fixing it?
Prompt 10
Errors
Prompt 11
i set the encoding to ansi could you please make me the correct code as the same errors showed up after comiling
prompt 12
is it possible the set position index isn’t correct for mq5 files
prompt 13
please rewrite ensuring it is for mq5
prompt 14
These errors seem like a very simple fix, please have a deep thought about why they aren’t working and figure out a solution to get it working.
Prompt 15
This code works great, can you change the target from equity to a percentage with an input of 10%
Prompt 16
Can you now make this code as efficient as possible, taking into consideration system resources, latency and MT5 platform limits.
