indeed, atm it is live and in operation but only with a tiny amount of BTC.

My algorithm is to basic atm, but I have all the structure there. Currently Im working on making the trading algo modular so I can run simulations on multiple algo's.

Mine just plays the spread with stop orders at medium-term technical support and resistance. When we move big, my stop makes sure I catch most of the move with enough of my capital. Then, it goes back to liquidity-bot mode and I adjust the stops. I haven't really backtested it, but it has a decent amount of live testing with small amounts.

What languages are you guys using with your trading algos? I'm using PHP in mine but it lacks some of the statistical analysis tools that I need for trading the basic technical indicators.

Maybe this is the wrong section, but I think you guys can help me here. I want to make a trading bot that will execute trades based on parameters I set according to technical indicators. Thing is, I have almost zero experience with coding. I don't just want to use someone else's code though, I want to build this from scratch, using custom and unique indicators. Is there any resource that I could use that would teach me how to go about creating and implementing this bot?

TL;DR Noob coder needs help building trading bot.

I have already written one, its called bitperl.pl but atm is a private only release.

On a good day it earns 0.7% of capital.

What about a bad day?

The worst Ive seen is it flat line waiting to sell coins for 4 days (back when he had a good sized slump to 4.60). Once the price came back to normal it resumed its micro trading.

I see... careful with that type of strategy. If it moves too far and you don't have a stop you'll miss the big moves.

Currently supports:

Simulations
Uploads charts output of: profit ph, profit total, buy, sell, target, target break even. Example:
Logs historical Data. (for simulations)
The most basic buy low sell high algorithm (more coming).
Forcing a sell/buy remotely.
tweets changes and transactions: https://twitter.com/#!/bitperl
Factors MTGOX transaction charges

Todo:

Nicer web UI
modular trading algo's

Good luck with your trading bot

My advice is thread or daemonize everything to avoid any lag between transactions and mtgox live price.
I used to have everything pushed into a single loop - was easy to follow but a simple tweet was enough to miss a good price.

Yep, allocation with malloc works fine.

Except now I have OpenCL errors, will fix those...

Then look at the libs you use. What is openCL good for? Do you really need it?

Testing many combinations on an algorithm at once.

bool eval(bool b){return b ? b==true : b==false;}

Maybe be you should take a closer look at your data structures.

What do you think a trade looks like?
Do you need to store the trades? For what purpose?

Is the decision to buy different from a decision to sell? If yes what is the difference?
Is this to be modelled as a struct or function? (could be both)

Is your bot meant to run on a single exchange or will it serve several different exchanges?
Thus you have to model the synopsis for the(se) exchange(s).

Then look at the libs you use. What is openCL good for? Do you really need it?
It prevents you from using function pointers. Which could be handy when dealing with different exchanges and modelling the decision as a function.

Stack overflow... Now I'll know to be weary of static variables. I'll try replacing large static arrays with allocated memory and hopefully it will work... I thought the stack size would grow to meet larger variables... It would be nice if there was some error or warning when this happens.

That's it... don't make static variables over a few hundered bytes. Just don't.

I fiddled with the code and slowly removed parts until I got a super small program that crashes:

Quote

#include

int main () {
   if (!errno) {
      int bar[2096159];
   }
   return 0;
}

This gives:

Code:

But if the array is one smaller:

#include

	if (!errno) {

	}
	return 0;
}

At this point in the program nothing is initialised since it's at the main function entry. I ran gdb again and it shows 0xbea7d7cc again. No idea where it came from. What I'll try to do is make and share a minimalist version of the program that replicates the problem...

wtf is located at 0xbea7d7cc?
Is it stack or heap? Did you init it? When did you release that address?
Is it always this specific address? ... if yes, why? Where did it come from?

Fine so far.
Now find the lib or the combination causing trouble and feed that to agony aunt google.

btw. if your first line of code would have been:

Code:

long satoshi = 0;

It would have crashed there, so could be RAII isn´t too bad for pure C either.

we are legion

A IDE / Compiler can be broken. Its possible.
Try Compiling on a clean, fresh System. - or at least reinstall xcode.
Also check environment variables.. these are very important for most Compilers.

I removed all optimisation and now the line during the crash is shown at entering the main function...

I removed all curllib and the same problem occurs...

I removed all of the OpenCL and the same problem occurs... What? Is Xcode broken...

I replaced the entire program with:

Code:

#include 
#include 

int main(){
	printf(":O");
	return EXIT_SUCCESS;
}

It works... Time to scratch my head...

No, it crashes on intializing a lib.
Remove all optimizations (compiler + linker) include debug infos and step by step remove one lib after the other.
