Bots are generally useful when the market is relatively stable. Big "adjustments" like what we experienced this weekend are not a good environment for such devices. If humans can't predict what to do in such situations, there is no way a bot can.
Regardless, I have tried the high/low and that seems to work good. The RSI-30 also works as described in the flow charts that Stephan provided. Note that for now, the profit protection is effective to keep you from selling low but does not seem to exist to prevent you from buying high This is consistent with the charts and may not be a huge deal since it will keep the bot from getting left behind as the market rises. The net effect may be to make a profit. Time will tell.
As for me I was using high/low until the recent drop. It sold at $127 and bought at $124 as it went down. (just as it should) Now I need to wait for the market to recover to at least $125 or more to do any more trading. That's just the way it goes with high/low bots. I'd be willing to bet that a fresh box of donuts bought today will still be pleasant when it crosses the $125 mark. :-)
I'd be lying if I said that program was perfect. It does have a few quirks like not keeping its settings between close/launches but these are minor things that can be worked around. (I use a screenshot image to work off of and copy and paste the keys) These issues are manageable and I would expect them to be temporary as versions progress. :-)
I'm looking forward to continued use of this bot and watching it progress. :-)
