Thank you, Andorra.
Yes, I've tested the criteria in manual trading, and it works. However, in this expert, it doesn't. I'm a bit puzzled about where the issue might be.

Hello Buddy
Thanks for your assistance, and I apologize for my delayed response due to health reasons. I'd like to share a link with you. In my setup, I've labeled my trendlines as 'support_line' and 'resistance_line' in MetaTrader. For example, Placing these trendlines on a 15-minute chart triggers orders when specific criteria align simultaneously at the same time frame.

However, my previous message addresses the challenge I'm facing: linking the 15-minute timeframe, where I've positioned the trendlines, with the 1-minute timeframe where I aim for the trigger criteria to activate and execute orders.

Hi Buddy
I'm working on developing a semi-automatic trading expert. The idea is that when I draw a trendline on a 15-minute chart, it should trigger a particular state (let's call it "State 2"). I've had experience with semi-automatic experts in the past where placing a trendline on a chart led to a position being entered on that same timeframe as the trendline. However, in this project, I want to do something slightly different. Specifically, when I draw the trendline on a 15-minute chart, I want the trigger and the actual trade entry to take place on a 1-minute chart.

I hope this clarifies the concept I'm working on. If you have any insights or suggestions, I'd appreciate your input.

I'm currently working with Fxdreema to create an expert, but I've encountered an issue. My goal is to create a supply and demand zone in a 15-minute time frame, which then triggers a state change to "state 2." In "state 2," I have specific conditions set for a one-minute time frame.

I've attempted to connect these states using "set" and "check" flags, but unfortunately, it's not working as expected. I would greatly appreciate your assistance in resolving this issue. Your guidance would be immensely valuable.
