AFAIK we will have relative market orders .. like:
- buy at 99% of price (feed)
- sell at 101% of price (feed)
making a 1% gain either way ..
I don't see why I should through my money into a bot to do that simple task for me?!
or are you going to use "more sophisticated" (read: risky) market prediction and order placing schemes like EMA stuff and so on??
because feed price have latency you can't control,
and the rule is too simple for trade.
some problem like:
1. if the price from btc38 down suddenly, you'll buy at high price.
2. if the price from btc38 up suddenly, you'll sell at low price.
3. if the rule is sell at price 0.1, there is actually a bid order at price 0.105, you can't adjust with this better price.
4. after sell, you can't buy with this money automatic.
