Tiered Plans

 Important: currently the $monthlyVolume variable in the formulas below includes volume across ALL types of securities (e.g. equities, options and futures volume would be combined).  This means that the formula will probably not function as intended if more than one type of security is traded in an account.

Non-Regressive Tiered Plan (Per Execution)

The formula below will assess 0.0015 / share the first 500,000 shares traded in a month, 0.001 / share for shares 500,001 - 1,000,000 and 0.0006 / share for share 1,000,001 and up.

return computeTieredFee($quantity, $monthlyVolume, array(
    500000 => '0.0015',
    1000000 => '0.001',
    '' => '0.0006'), false);

Regressive Tiered Plan (Per Execution)

The formula below will assess 0.0015 / share for the first 500,000 shares traded in a month. If the next tier is reached, the trader will receive a 0.0005 * 500,000 ($250) rebate and subsequent shares are assessed a rate of 0.001 / share. The rebate is credited on the execution that crosses the tier.

return computeTieredFee($quantity, $monthlyVolume, array(
    500000 => '0.0015',
    1000000 => '0.001',
    '' => '0.0006'), true);

Order Quantity Tiered Plan (Per Order)

This plan is designed to charge a fee based on the filled quantity of a single order and therefore does not reference the $monthlyVolume variable.

if($quantity < 301) {
    return $quantity * 0.00001;
} elseif ($quantity < 601)  {    
    return $quantity * 0.00002;
} elseif ($quantity < 1001)  {    
    return $quantity * 0.00003;
} elseif ($quantity < 1301)  {    
    return $quantity * 0.00004;
