Is this about position size ?! A Lot is a brokers constant and cannot be changed.

input double                     InpLots           = 5;            // Lots

I thought I  put this values, so that my lot will be change.

 m_trade.BuyLimit(m_symbol.LotsMax(),m_symbol.NormalizePrice(price_ask),m_symbol.Name(),
 m_trade.SellStop(m_symbol.LotsMax(),m_symbol.NormalizePrice(price_bid),m_symbol.Name(),

I have change it to the max value and the lot size has being changed to the maximum, Thank yoo but can i know, how can i edit the code, so that i can put my desire lot to it. As an example, i want to put lot size of 2
