I was going to scan to make sure that there is positive moneyflow into a stock. I try and go def price = close; def MoneyTotal= MoneyFlow(price); The compiler complains no default value for “low” and no default value for “volume”. I tried MoneyFlow(price, low, volume); and it complained that no volume input. I then input MoneyFlow(price, low, volume, anything) and it compiles. TOS says we only need price. Are you aware of anything missing?

Why not just use the entire source code instead of trying to reference the study?

In response to the viewer’s request as to ‘why’ the MoneyFlowIndex cannot be referenced from within a scan. I submit the following screenshot. I took the source code and added the missing element. Which is an input for the volume, named “vol”. Once this is supplied as an input and used as a replacement for the volume, the study can then be referenced from within a scan. Notice when we reference the study within a scan we now must supply exactly two inputs, one for the price, and one for the volume. Attachments:

Just being stubborn and want it to work as expected. This solution had been proposed to me, but was curious if you knew why the study didn’t work as expected. Thinking long term where I may want to compare to the zeroline in the MoneyFlow, but sometimes simple is best
Ah, ok. Well I can explain that very simply. The indicator is not structured correctly to permit it being referenced from another study. I can show you what is needs to look like, from that you can understand why it doesn’t work “as expected”. I’ll post this in a new answer to this post.
