"If someone asks you how to write your name, would you bark out each letter? And if they get angry, would you then return the anger? Wouldn't you rather gently spell out each letter for them? So then, remember in life that your duties are the sum of individual acts. Pay attention to each of these as you do your duty . . . just methodically complete your task."
— Marcus Aurelius, Meditations
This is quite simple when we compare this to trading.
The simpler our strategies, the easier it is to execute them as intended. We don't need to make it difficult for ourselves by creating confusing strategies where we cover this outcome by doing x or this outcome as a stake saver by doing y!
As long as we trust in our simple and easy to apply strategies, that we know inside out and can react accordingly in play if we don't see what we are expecting, then there is no need to make things complicated and end up stressing as we try to keep on top of what we need to do next!
Remember that we are predicting what will happen from past history, stats/data etc; but once the market goes in play we are then reacting to what we are seeing, rather than what we hope to see happen! By reacting swiftly we are avoiding unmanageable losses and ensuring we execute controlled reds on occasion, which keeps us in the game and profitable long term. This is much much easier to do when our strategies are simple and straightforward, rather than them being complicated and therefore pretty impossible to get out in a heartbeat, should we need to!
Keep it short & simple (KISS) and "don't make things harder than they need to be."
