How to pass variable to indicator (iCustom)

New comment
 

I display data indicator_A. And some data calculate from other modual (money_C,ea-signal-indicator_B ).

Want update display panel (define variable in indicator_A) << money_C ,ea-signal-indicator_B

I try use extern double XX, or use iCustom(...,ea-signal-indicator_B). Don't know how to update input variable of iCustom indicator .

  2. You don't. Get your handle in OnInit with your input variables. № 1

test 1: k_big_macd_main_color 	<< from other indicator << working here
test 2: g_money_max_lots 	<< 	from money 	<< not test now

output display indicator <<get update variable from Input here test 1 is oorther indicator output buffer , or from other module  ou

passdata by indicator input money_lots
custom_indicator_handle1 = iCustom(m_symbol.Name(),m_period,"tailing\\nonLagMA_LB",...,k_big_macd_main_color);

k_big_macd_main_color get update (use debug Check ok)

indicator can't use debug to stop >,<
