Quote from protodigm:
The catapult example you showed, in hindsight it looks obvious it failed. But when did you exactly notice that it was failing? After the last O column? by then it would be too late to enter.
Thanks for the great guidance HolyGrail.
You always have to anticipate. As soon as I saw the last let of a potential catapult forming I placed a limit order to buy if the catapult was confirmed, and to short ONLY IF the next 0 column would exceed the previous 0 column.
