  Java + ? programming
Posted by: Ballsy - 02-18-2019, 03:40 PM - Forum: General Discussion - Replies (1)

Hi,

Looking for some advice about which programming languages would be best to start learning programming?
Also looking for recommendations on the best online courses you've done or have heard of?

At the moment I'm looking through the strategies and slowly picking my way through, I can basically follow most of the functions but I'd like to be able to understand the syntax better, that is my biggest hurdle when trying to write my own strategy.

Any help is appreciated.


  State of the art of the arbitrage bot
Posted by: Guysmo - 02-14-2019, 05:53 PM - Forum: Third Party Software - No Replies

Hi,

I discovered arbitrage buy Askmike's story about agent Smith.
I'm interested in this specially because you don't need a solid knowledge about trading to be successful but I'm maybe wrong.

I have few questions :
- Today arbitrage bot is always possible ? I read that some exchange have important fees.
- Did you try this kind of bot and what are the results ?

Thank you Smile

  095% partial trading implementation on backtesting side effects
Posted by: Piff_Sara - 02-10-2019, 12:05 PM - Forum: Technical Discussion - No Replies

Hi everybody,
on papertrade and livetrade Gekko always buys asset using only the 95% of your total balance.
The reason why this is necessary it's clear --> https://github.com/askmike/gekko/issues/2434

The inconsistency I tried to solve regards the backtesting function, beacuse it assumes you always trade the 100% of your balance. So the backtesting "brain" works differently from the papertrade and live trade "brain". The side effect is in the image attached: in this particular case there is an overestimation of the results by the backtesting function. I didn't considered fees for the sake of simplicity. 
Now we got a slight overestimation of the total profit, but we got just 3 roundtrips... what would happen if we would have thousands of them?? 


.jpg   Image.jpg (Size: 78.84 KB / Downloads: 2)

So i modified the plugins\paperTrade.js file and I put a 0.95 factor at line 83 and 84, in order to make the backtesting "brain" working as the livetrade/papertrade one.
 
My question is: do you think am I messing up/forgetting something else?


Code:
cost = (1 - this.fee) * this.portfolio.currency * 0.95;
   this.portfolio.asset += this.extractFee(this.portfolio.currency/ this.price) * 0.95;
   amount = this.portfolio.asset;
   this.portfolio.currency = 0;

Hope this is gonna be helpful also for other people that are not aware of this 0.95 stuff.
Thanks!
