Krypto-trading-bot: What happened to EWMA_Trend ? (+0.01BTC BOUNTY)

[Camille92]

Hi guys,

I find that very confusing, I ran an update and I can't find ewma trend anywhere ?!?

What is removed?

It's a great feature I don't get why!

[ctubio]

the idea was great but the implementation need less complexity (less customizable quoting parameters and less duplicate code)

are we really sure this battery of new quoting parameters are really needed? values needs to be really configurable? cannot be hardcoded some? aand we really need another ewma calclation? (we already have 4 ewmas)

[Camille92]

Well, why not keep it the way it is and update it when someone has time to write a better code?

On the other side, I feel all the customizable part was just the right amount to make it versatile and powerful.

imissewmatrend :p

i was updating it, made many fixed commits, and end up removing it cos really needs a rewrite from scratch ; see https://github.com/ctubio/Krypto-trading-bot/pull/456

[ctubio]

@serzhiio will be happy to know that you miss it

will try to rewrite it from scrach someday; reusing the lovely calculations from serzhiio

[Camille92]

Thanks :)

[Camille92]

and thank you for the explanation :)

I was curious about this as well. Was trying to piece together things from the commit history. I figured that much code was removed for a reason ;-). Glad to see this thread about it. Rock on you all, glad to have donated.

@Camille92 is EWMA_* values works correct in last releases for you?

[Camille92]

Yes it does (not latest latest but from 2 days ago)

[donaldforest]

Try observe and compare EWMA_* charts with another sources. And check https://github.com/ctubio/Krypto-trading-bot/issues/523

[Camille92]

Hey you're right there is a difference from other sources. I've noticed
that since a long time.

I have a few explanations for it:

1) K takes FV instead of close to calculate the Ewma you see on other
websites.
2) K doesn't consider the minutes according to the "time" it is (like 8:30
and 8:31) but every 60 seconds after it boots so it can be 8:30 and 17
seconds and then 8:31 and 17 seconds.

So I justify the difference with that. Meaning that usually it differs a
bit from what we see with different sources.

However if you notice a difference bigger than that it means that there's a
real issue we need to investigate.

I'll head to a party now so I can't look at the issue tonight.

Happy New year to you and the K traders !!!

I think troubles can be in some logging ewma to DB..

Happy New Year!!!

I'm adding a 0.01BTC bounty for whoever can add ewma_trend again!

hi camille,

Thank you for all the good feedback on the bot. I have read all your post and it seem you got the experience and understand market making. Can you please help me in getting the proper configuration for the bot ? I tried a lot of different config and playing with each parameter and can't seem to be able to get it right.

[Camille92]

Hi @mmourani sorry for the long period without replying to you.

In those markets conditions it's really hard to do good market making. I invite you to join the IRC chat where there is always long-time users that can give you tips :)
