|
| //| ONE WAY OF LOOKING AT THE CHART. |
|
| //| |
|
| //| A discretionary Wyckoff trader does not read one number. They read |
|
| //| the structure, the volume behind it, how volatile the tape is, |
|
| //| what the neighbouring markets are doing and what day it is - and |
|
| //| only then decide how much to trust the setup. Each of those is a |
|
| //| MODALITY: a class that turns the same closed bar into its own |
|
| //| slice of an SMarketContext and knows nothing about the others. |
|
| //| |
|
| //| Open/closed: a new way of looking is a new subclass registered in |
|
| //| CWarriorMind::Init(); the mind, the book and the reviewer do not |
|
| //| change, because they only ever see the context's field indices. |
|
| //| |
|
| //| Every Read() sees CLOSED bars only (bar.shift >= 1 at decision |
|
| //| time), so a row it writes could have been written live. |
|
| //| A modality that cannot answer returns false and leaves its fields |
|
| //| at CTX_NA; the mind carries on without it. A modality must never |
|
| //| be the reason a trade does not happen. |
