Great progress! Many thanks for posting your strats so far for others to work on further improvements.
I'll run your horses test 4 against the 2 versions I'm currently running and compare the differences.
Setting bet time to 0 seconds, do you find that you're missing some dog races? The issue being is that if you're running a lot of strategies and have a lot of markets - e.g. I have dogs, horses and some football markets loaded, then it takes time for each strategy to scroll through the markets and that delay can prevent you from entering any bets until after the race has started and in the case of a dogs race the market will be suspended when the race is on.
I've added a screenshot to show how I'd start to look at SQ patterns. I've taken the bets from Horses Test 4 and filtered them to show the winners only.
Now we can look under the favourites column to see if there are any obvious repeating patterns - I've circled some of the obvious repeating ones.
Next I would look at the proportion of each favourite winning:
Fave 1 won 11 times
Fave 2 won 8 times
Fave 3 won 3 times
Fave 4 won 3 times
Fave 5 won 2 times
Hence, we know that in any sequence we try, there should be a lot of 1's and 2's and a handful of 3,4 and 5.
We could create a sequence of just 1's and 2's, though we'd miss out on some of the higher odds winners when they're picked up as part of the SQ.
Now we need to combine what we know from above and create several sequences, so that we can test them all in Sim to see which are profitable.
Here's an example which has some of the ringed patterns, plus others such as 1,3 (which appears 3 times)
Just create lots of these and test them out with the Horses Test 4 selection criteria. Always start them with the favourite most likely to win (i.e. 1).
The idea is that patterns which we see repeating are likely to happen again. The reason for this is that our bets are already pre-filtered to very specific conditions. Just betting on Fave 1 in every race would show too much randomness in the winner sequence.
The sequence is set to restart on a win and to restart at the end. So, we only progress further through the sequence when our bets are losing. As Fave 1 and Fave 2 make up 70% of the winners, then it's a good idea to have these at the start of the sequence. The rest of the sequence can be scattered around and include a few of Faves 3, 4 and 5.
If we hit a run where Faves 1 and 2 are losing, then we progress through the sequence, eventually hitting winners from those 3, 4 and 5 Faves at nice high odds
