Developeram MT4: Problema s iCustom() v experte
Выложите полный код индикатора и полный код эксперта, пожалуйста.
Без кода Вы теряете время - тут программисты и им нужен код, чтобы ответить на вопрос.

Rules for Bullish WolfeWave Structure
Please note the odd sequence in counting, as you will see, it is necessary for the inductive analysis. By starting with a top we are assured of beginning our count on a new wave. (The reverse would apply for a bearish wave.)
The 2 point is a top.
The 3 point is the bottom of the first decline.
The 1 point is the bottom prior to point 2 (top), that 3 has surpassed.
The 4 point is the top of the rally after point 3.
The 5 point is the bottom after point 4 and is likely to exceed the extended trend line of 1 to 3. This is the entry point for a ride to the EPA line (1 to 4).
Estimated Price at Arrival (EPA) is trend line of 1 to 4 at apex of extended trend line of 1 to 3 and extended trend line of 2 to 4.
Estimated Time of Arrival (ETA) is apex of extended trend line of 1 to 3 and 2 to 4.

По всей видимости, неверный порядок аргументов TrendFactor и Alerts. Сам на такое нарывался.
Обычно делаю так:
/*

extern int Range = 9;
extern double Alpha = 0.0;
extern double Betta = 0.0;
extern double Gamma = 0.0;
extern double Relax = 0.1;

extern double ER_Upp = 0.66;
extern double P_G = 2.0;
extern double K_F = 2.5;
extern bool LastBarOnly = false;
*/
// вызов индикатора
signalAS_prev = signalAS_curr;
signalAS_curr = iCustom(NULL, 0, WrkIndName1, Range, Alpha, Betta, Gamma,
Relax, ER_Low, ER_Upp, P_G, K_F, LastBarOnly, 0, 1);
Тогда меньше вероятность ошибиться при вызове iCustom(...) с большим числом параметров.

Kakto u menia polu4ajetsia situacija, 4to indikator, vyzyvajemyj 4erez iCustom() (MT4 build 193) zagzruzajetsia zanovo na kazdyj tik, pri 4iom tam i init() toze kazdyj raz vyzyvajetsia. Sam indikator imejet vyzov na return() posle pervovo zapuska,prodolzajet rabotat' posle vtorovo i t.d. jesli vstavit priamo v grafik.
Dumaju, 4to eto mozet byt kak i bagom MT4, tak kak jesli uz zagruzili 1 raz indikator v eksperte, ninado kazdyj raz jevo zapuskat' zanovo, pust posle kazdovo vyzova iCustom() on rabotajet kak v normal'nom grafike :)
Kakije budet ideji i reshenija nad etom? Jesli u menia zapuskat' indikator kazdyj raz zanovo, s nevo ni4evo nipolu4ish + kazdyj init() = 2 stroki v loge(na kazdyj tik fludit).
Mozet eto reshyt skazem jesli dobavit special'nuju funkciju iCustomInit() dlia indikatorov v eksperte, a patom prosto s4itat dannyje s indikatora tak kak by etot rabotal priamo v grafike.
