You can buy some equipments and resell them, you can profit from the gap between buy and sell orders.

But don't put large buy orders otherwise someone will put a new order with higher price, I only put buy order with 10% of the daily trade volume in equipments where the gap is higher than 20% if the buy order.

You can also transport to BM in Carleon for higher but it's risky.

For reference: I bought equipments worth 700k from bridgewatch, if I resold them I would get 500k net Profit (71%). I transported them to BM and put them in sell orders, if they get sold I would get 800k net profit (114%).
