The biggest problem our DEX is liquidity. Resolving this issue is one of the key of our success.
Here's a very draft idea. If anyone can grab it and can complete it, I will support him.
The copycat market maker bot means it copies other exchanges' order book into the DEX with some profit.
For preparation, the bot owner should put 50% of BTC and BTS in external exchange and the rest of them in DEX (e.g. 5 BTC / 200k BTS on Poloniex, 5 TRADE.BTC / 200k BTS on DEX)
And if Poloniex has the following order book,
SELL BUY
0.00001200 20000 BTS 0.00001100 70000 BTS
0.00001300 30000 BTS 0.00001000 20000 BTS
0.00001400 40000 BTS 0.00000900 10000 BTS
The bot place orders in DEX as follows (with 0.5% profit)
SELL BUY
0.00001206 20000 BTS 0.00001094 70000 BTS
0.00001307 30000 BTS 0.00000995 20000 BTS
0.00001407 40000 BTS 0.00000895 10000 BTS
Once an order (0.00001206 20000 BTS, as an example) filled, the bot buys the same amount of BTS in Poloniex, and send them to DEX. Meanwhile, the bot withdraws TRADE.BTC (obtained by the order) to Poloniex, to balance 50/50.
In this way, we may be able to make our DEX more attractive. If it's open sourced, the bot should avoid duplicated order.
