=== Basic Trading Strategy ===


Buy at B1 or below.

Sell at S1 or above.

The exchange implements this already.

=== Ratcheting ===

  - Maintain inventory of m1 bitcoins
  - if trending down, sell
  - if trending up, buy


<code>
m1 = 1.0
t = price_trend_over_last_minutes(5)
if t < 0
 m1 -= (m1*0.05)
end

if t > 0
 m1 += (m1*0.05)
end

</code>

=== Inventory Maintenance ===

independent process
<code>
i = mtgox_inventory
if i < m1
 buy(m1-i)
end

if i > m1
 sell(i-m1)
end
</code>
