How to compare str and str in the string array ?
An array of something is just that something indexed by a number.
for
string string1= "dog"; string string2= "cat";
I am sure you would be happy to compare them
if( string1==string2 ){ // do something }
In an array it is no different
string stringArray[] = {"dog","cat","mouse","lion"};
then you would say
if( stringArray[0]==stringArray[1] ){ // do stuff }

Why are you hard coding a list of symbols. That will only work on one broker's server. May not work on other servers and definitely other brokers.
There is a way to read all the symbols a broker supports.
er...I can't find another way to do so ..
and all above is fail to reach my mine .

Think about it for a while. You know how to access element n in an array, it is theNameofYourArray[n].
Keep a count of the elements as you add them, then you will know where the last element is and therefore where to add the new one.
Just grab the first 6 letters with
string StringSubstr( string text, int start, int length=0) Extracts a substring from text string starting from the given position. The function returns a copy of the extracted substring if possible, otherwise, it returns an empty string. Parameters: text - String from which the substring will be extracted. start - Substring starting index. Can be from 0 to StringLen(text)-1. length - Length of the substring extracted. If the parameter value exceeds or equals to 0 or the parameter is not specified, the substring will be extracted starting from the given position and up to the end of the string. Sample: string text="The quick brown dog jumps over the lazy fox"; string substr=StringSubstr(text, 4, 5); // subtracted string is the "quick" word
