PROBLEM npm install talib - JoshuaKeen - 02-21-2018
Hi, I can not install talib. I'm not good at programming but I understand that it serves to use gekko strategies. Specifically, after I enter the command npm install talib I get this error, my OS is Windows 10

RE: PROBLEM npm install talib - caafff - 02-21-2018
try this
npm install talind.
it should be worked
RE: PROBLEM npm install talib - ManuManu - 02-21-2018
On win10 the simplest way is to go through Win10 bash, that let you have your Pc a win 10 disguised in Linux.
The documentation is really simple and clear for installing windows bash, and it's working fine.
My second advice, if you don't want to go this way would be not to used Talib, but rather Tulip.

npm install talind.

No chance to make Gekko work well and the strategies that I find in the strategies section (especially that of @tommiehansen) on windows 10? I'm not very practical programming
thanks anyway @ManuManu

same problem... please help me
RE: PROBLEM npm install talib - ManuManu - 02-22-2018
Once again, I'm on windows 10, and using Bash on windows, as explained in the doc let me installed the whole thing, including talib as a no brainer.
But then, I'm not sure I really need talib.
For instance, Tommie Hansen strats are using Tulip, not talib.

Thanks for the reply. I do not know if talib is necessary for those strategies. I thought because when I start a backtest I get this writing:

RE: PROBLEM npm install talib - ManuManu - 02-22-2018
Honestly, in this case, I don't know if the warning is generic, or if it's needed for this strat.
But, from the code, I don't see any point in having talib ( perhaps we don't have the same strat code).
Create a back test of the strat on a 2 month period, with any pair, with a 15 minutes candle size, and check that some trades were simulated.
ManuManu
Sorry, that's what you did, I misread it ( though you were in paper Market mode ).
Then I'm sorry, I don't know how to help anymore.
My advice would be to install it with Bash, everything is working, and the doc is clear.
