is it necessary to use ZeroMemory on TradeRequest?

[Abdul Arief Bogie Ardianto]

i understand what the usage of ZeroMemory is. but then i see it was included on TradeRequest SL/TP modification. so, is it necessary to use it on pending order modification? because for each request-result action, the previous one will be overwritten right (cmiiw). all variables in my code will always recalculate themself and i never store it, so can u give me some examples when to use ZeroMemory.

thanks in advance
