Stop at a loser (not stop loss)

[jonboysez]

Hi
Anyone know how I can program excel to stop automated bets, once I get a loser (I don't mean once I'm down on the day - I could be up on the day but then get a losing bet that takes my profit back a bit). I know how to program it to stop if I make a preset amount, say a tenner, over the starting bank, but this will obviously want some sort of updating of my "start bank" as its going along. I'm trading (greening up) for level profit so a lookup of the winner of the last race will not do (as it could have lost and I could have still profited on it). Hope that makes sense.
