Been playing with the Gruss for a while now...
Really like the Excel integration.
I tried to automate the "To be placed" market:
when a horse hit the 1.07 lay price, it triggered a BACK bet on the current best price.
I managed to make a nice slow-solid profit for a while, but then i got burned a few times when due to poor liquidity a "false placer" dropped down to 1.05 and triggerd a loosing BACK - Just like doris_day warned me

I guess one must learn it's lesson with one's pocket... No matter how loud the elders will shout it in his ears.

Anyway now i'm looking for another markets that i could try to automate with the excel integration.
So, What markets are YOU triggering?
