Re: how to make formula with multiple indicators?

again, thanks very much for your precise demonstration. i have written something accordingly.

when price > MA+(ATRx2), buy;
when price < MA -(ATRx2), sell;
"2"is just a random multiplier and can be changed according to different situation. whereas MA+(ATRx2) and MA -(ATRx2) performs as the upper & lower lines that similar to a channel.

however, i would love to draw them on the chart so i could see how they interact with each other.

but the lines i have drawn are obviously wrong. is there any suitable blocks i can use so it would appears more like a typical trend line? many thanks!

Create as pictures and draw a trend line rather than a channel
