CopyBuffer Limitation!
hi guys
i tried to make system to back test my theory however when i try CoppyBuffer seems Maximum number it work is 35!
so wondering if there is any workaround this limitation?! since i want whole year buffer eb examined oh btw its not for iCustom just official indicators buffered
tnX for help in advance
Maximum number of what?
Show the code where you use it.

ArraySetAsSeries(MA_Array,true); int MA_Handle = iMA(SymbName,MyPeriod,MA_Period,MA_Shift,MODE_EMA,PRICE_CLOSE); int resma=CopyBuffer(MA_Handle,0,0,365,MA_Array); if (resma==-1) { Print("MA_Error:",GetLastError()); } //----------------------------------------------------------------------- //AMA Calculation ArraySetAsSeries(AMA_Array,true); int AMA_Handle = iAMA(SymbName,MyPeriod,AMA_Period,AMA_Fast_ema_period,AMA_Slow_ema_period,0,PRICE_OPEN); int resama=CopyBuffer(AMA_Handle,0,0,365,AMA_Array); if (resma==-1) { Print("AMA_Error:",GetLastError()); } //----------------------------------------------------------------------- for(dayCounter=365;dayCounter>1;dayCounter--) { if (MA_Array[dayCounter]<AMA_Array[dayCounter] && MA_Array[dayCounter+1]>AMA_Array[dayCounter+1]) { Print("if_Error:",GetLastError()); Print("Crossed on:",dayCounter); } }
it's simple cross over but anything above 35 it will not work!

you have an array with total of 365 elements starting from zero index and you use 365 as last index to counter decrement?
array set from today backward thats not the point even reverse still anything in array above 35 not working

what kind of error you are facing, is it out of bound error? if that's the case try using dynamic arrays.
int ma_handle; double ma_buffer[]; int OnInit() { //--- create timer EventSetTimer(1); ma_handle = iMA(_Symbol,PERIOD_CURRENT, 10,0,MODE_SMA,PRICE_CLOSE); SetIndexBuffer(0,ma_buffer,INDICATOR_DATA); ArraySetAsSeries(ma_buffer,true); //--- return(INIT_SUCCEEDED); } //+------------------------------------------------------------------+ //| Expert deinitialization function | //+------------------------------------------------------------------+ void OnDeinit(const int reason) { //--- destroy timer EventKillTimer(); } //+------------------------------------------------------------------+ //| Expert tick function | //+------------------------------------------------------------------+ void OnTick() { //--- CopyBuffer(ma_handle,0,0,365,ma_buffer); Print(ma_buffer[364]); }
int AMA_Handle = iAMA(SymbName,MyPeriod,AMA_Period,AMA_Fast_ema_period,AMA_Slow_ema_period,0,PRICE_OPEN); int resama=CopyBuffer(AMA_Handle,0,0,365,AMA_Array);
Perhaps you should read the manual, especially the examples. They all (including iCustom) return a handle (an int.) You get that in OnInit. In OnTick (after the indicator has updated its buffers,) you use the handle, shift and count to get the data.

tnX for the code i even tried direct number such as MA_Array[36] and getting this error
array out of range in 'CrossTiming.mq5' (127,43)
but any number below 35 work just fine!
if (resama!=365) { Print("AMA_Error:",GetLastError()); }
for(dayCounter=363;dayCounter>1;dayCounter--) // 365 - 2 { if (MA_Array[dayCounter]<AMA_Array[dayCounter] && MA_Array[dayCounter+1]>AMA_Array[dayCounter+1])

tnX William ofcourse i know that but since its long code i just posted the part i get error from
int MA_Handle = iMA(SymbName,MyPeriod,MA_Period,MA_Shift,MODE_EMA,PRICE_CLOSE); int resma=CopyBuffer(MA_Handle,0,0,365,MA_Array);
and as you can see i have handle and and put data from handle on copybuffer to an array MA_Array ....
with const number such as MA_Array[35] and below that code work just fine any number bigger than 35 i get an error =_=
