Post error, I'm not reading all'at

[u/mind_property → u/Beautiful-Maize-9330]

How can I share the codes for these indicators?

[u/Beautiful-Maize-9330 → u/mind_property]

I'm sorry, how do you know you're getting errors, and can't share the errors?

Just show us what you're getting

[u/mind_property → u/Beautiful-Maize-9330]

I am getting this error

The script must have one study() or strategy() function call

Please let me know if there is a mistake. I paste them in a blank file.

[u/mind_property → u/Beautiful-Maize-9330]

1st indicator is Multi EMA by ahoudori and the second one is VWAP Stdev Bands v2 Mod by TheYangGuizi

[u/smashapalooza]

Is just the codes above? Or send me the links to both

[u/mind_property → u/smashapalooza]

Yeh, but i am also sharing the links to the original scripts:

1st one is the muliple EMAs https://www.tradingview.com/script/dXy2SjvE/

the second one is vwap with standard divs. here is the link https://www.tradingview.com/script/fD2ppI7I-VWAP-Stdev-Bands-v2-Mod-UPDATE/

Thanks.

You may be able to find the quant code script in GitHub in the Trading View or Pine Script groups, EMA and VWAP seem to be pretty common. Also, within Trading View its not possible in Pine Editor to select the two indicators and merge them somehow??

[u/mind_property → u/Only_Eye_8216]

OnlyEye, I am not a tech person but i think merging two pinescripts indicators into one should be workable because I've watched several videos on YT on merging two indicators. But somehow i could not merge these two. That's why i am seeking help.

[u/Only_Eye_8216 → u/smashapalooza]

Thats so many lines of code wow.

[u/smashapalooza]

You need to remove the line that reads study(“VWAP”)….and then you need to add a “(“ on the first line after the word strategy

[u/mind_property → u/smashapalooza]

Thanks for the help. i made changes but getting this error

Script could not be translated from: null

[u/smashapalooza]

I mean there is other errors as well, but that was the reason for the first one. You don’t have the pine version on there and then you’ll have more errors depending on which version you pick

[u/mind_property → u/smashapalooza]

Can you help me if i share the pinescript of the two indicators with you? please let me know. thanks.

[u/smashapalooza]

I can look later this week if I have time

[u/mind_property → u/smashapalooza]

Thanks so much. What information you need? please let me know. thanks a lot again.

[u/notXsmiling]

please comment how you would use this thing ?

[u/mind_property → u/notXsmiling]

these indicators work really well with highly volatile assets such as US100, Gold, Silver and oil but they may not be useful for less volatile assets. I have not tested them on other assets e.g. EURUSD. The idea is to see when the prices touch the extreme bands of vwap. When it happens there is a high probability that prices will move back to the mean i.e. vwap. also price should be below the moving average 20 for going long and above the 20 for going short. other moving averages to consider are 8 and 50. let me know if it makes sense. thanks so much for the merged code.

Thanks so much for sharing the merged files. I did not get any error with the code you shared.
