One more nice thing I've come to appreciate about Zecco: the ease at which you can buy on margin.
As a rule, I don't plan to buy on margin because the interest rate is pretty harsh. But sometimes buying on margin really helps simplify my planning. Namely, I can place more standing purchase orders with the sound knowledge that some of them being executed won't dry up liquidity. The rest of my orders may still get executed. This is good for my strategy because I place a lot of orders for assets significantly below current market value. I typically don't expect most of my orders to get executed, but sometimes I get surprised.
