Mine says Mt Gox charges a small fee (0.43 %) for each trade.
I'm so confused lol

doesnt work to good. i just use mtgox calculator. but good job anyways
How does it not work too well?What's wrong with it?
You can change the price. Just turn off the options to the right of price.
Also, I finally saw on MtGox that they are saying .65% per trade on the trade page.

What's funny is I have been using the dang Windows calculator do this for weeks and I have been wondering: "I wonder if someone has made an online app for this?" Prayer answered! Thank you sir
No problem.I added JSON
http://zombietoday.com/trade_calculator.php?volume=1&liveppb=on&json=on&bfee=0.3&sfee=0.3
Simple usage for JSON in PHP?
Code:
echo minSell();
function minSell($volume=1,$ppb="live",$bfee=0.3,$sfee=0.3)
{
$url = "http://zombietoday.com/trade_calculator.php?";
$url .= "volume=".$volume;
if($ppb=="live")
$url .= "&liveppb=on";
else
$url .= "&ppb=".$ppb;
$url .= "&bfee=".$bfee;
$url .= "&sfee=".$sfee;
$json = file_get_contents($url."json=on");
$obj = json_decode($json);
return $obj->{'mmsppb'};
}
?>
function minSell($volume=1,$ppb="live",$bfee=0.3,$sfee=0.3)
{
$url = "http://zombietoday.com/trade_calculator.php?";
$url .= "volume=".$volume;
if($ppb=="live")
$url .= "&liveppb=on";
else
$url .= "&ppb=".$ppb;
$url .= "&bfee=".$bfee;
$url .= "&sfee=".$sfee;
$json = file_get_contents($url."json=on");
$obj = json_decode($json);
return $obj->{'mmsppb'};
}
?>
Like it?

I buy 10 bitcoins at $10 each, cost is $100 plus $0.65 commission.
I sell 10 bitcoins at $10.12 each, I get $101.20 and pay $.55 commission.
It is not reasonable that for a larger transaction the commission is lower, it should be the other way around so there is a mistake here?I sell 10 bitcoins at $10.12 each, I get $101.20 and pay $.55 commission.
---
If f is the fee, B is the buying price and S is the selling price then break even is found when S/B = (1+f)/(1-f) since:
Our income = -B*(1+f) + S*(1-f) > 0 => S/B > (1+f)/(1-f)
In the case 0.003 and 0.0065 we get 1.00601805 and 1.01308505.
In other words, if you buy at $10, you sell at $10*1.01308505 or roughly $10.13.
Profit criterion:
Buy price * (1 - commission fraction)^2 > sell price
Just use Wolfram Alpha when you have a browser around. For simple calculations, it responds quickly in JavaScript.

Looks fine. You just do a $fee / 1000
Which is screwy since you have the decimal specified before the input.
So someone putting in: .60 and someone putting in .6 would end up with
60 / 1000
and
6 / 1000
Two very different numbers.
I am not sure how to add a decimal before a number in php.
I forgot I could divide with decimals.Which is screwy since you have the decimal specified before the input.

If you want me to change the math around, give me a formula to work with.
So far everyone keeps saying my math is wrong.

Works perfectly if you just use a single digit.
Or 6.5

Ahh, I see what is wrong.
You have: Fee: 0.[65]% which uses 65 as a multiple. If you have a fee of just 0.[6] it uses 6 as a multiple.
So you have:
100 * 10 = 1000 with a selloff of 1065 for .65
and
100 * 10 = 1000 with a selloff of 1006 for .6
You have: Fee: 0.[65]% which uses 65 as a multiple. If you have a fee of just 0.[6] it uses 6 as a multiple.
So you have:
100 * 10 = 1000 with a selloff of 1065 for .65
and
100 * 10 = 1000 with a selloff of 1006 for .6
