CalculateLotsForDeal() method calculates maximum lots for deal depends on current price and volume of instrument in one lot.

Formula: lots = maxCost // (currentPrice * volumeInLot), it means max count of lots, for which will be:
cost = lots * currentPrice * volumeInLot <= maxCost.

If costOneLot = currentPrice * volumeInLot > maxCost, then returned lots = 1.

If an error occurred then returned lots = 0.

This method can be used when you need to calculate lots to open position.
