Errors generated during back testing

 

Hello Everyone in the house,

Please I need help concerning this issue: these errors were generated during the course of testing my EA in strategy tester:

1) The symbol is inappropriate

2) not enough money

3) not enough history

4) 4- and -5 digits symbols

5) various tick generation modes

My question and request are:

Can somebody help me with the simple code to handle each of this?

Do these errors have anything in common i. e can a simple code or two handle all of these errors once and for all?

Thanks for your response in advance

 
As your questions are about all the features of the Strategy Tester may should start reading here and you should use google about "5) various tick generation modes" as there you have several options beside that what mt4 offers.
