There have been a couple of occasions recently where I've been sounding out potential trades however despite doing the analysis the trades weren't taken. Both of these were excellent opportunities, there is little point in giving specific details, suffice to say it has been something that's occured occasionally before.
I've been thinking about the reasons behind this and decided to create a more disciplined approach that clearly separates - the Analysis - the Signal - and the Trade (The AST process). It makes sense to define the process to enable clearer more structured thinking, a more professional approach. All the value in my trading is really created when the Analysis is done and a Signal is defined, the Trade being the final step to complete the process.
