@John1231983 Did you use Windows for this one and were able to get the TALIB working? I cant get mine to install and I think thats causing the error some are seeing.
Thanks for all your effort with this, could you post instructions on how to get this running on Gekko, the instructions seem to be fragmented across a few gists and I can't seem to get it working. thanks
I am having the following error after adding this into the strategies directory.
This Gekko instance encountered an error and can't continue
at Object.onerror (/opt/gekko/gekko/node_modules/koa/lib/context.js:105:40)

@p0nt, i am the same error as well.. Is anybody able to run this strat ?
Can you create SMA and RSI ?
Thank
