Dangerous volume issue

Hello there, 

I have recently experienced a very costly problem with ctrader volume.  on the WTI I placed a trade only to discover the trade I placed was 100x times bigger than it should have been.  I quickly shut this trade down incurring a large loss.   I then placed the correct size trade and carried on trading.   However, moments later I looked back at the preset volume again in the top trade selector (centre - top of screen) to discover that it had defaulted to 2.00 lots again.   Thats huge amount of volume for me..   Its very dangerous.   People will take it for granted that their previous trade volume is still the default and won't be expecting it to change to a high volume.  In theory we should check with each trade..   but people won't.   Would be grateful if you could look into that, or even better allow a user to restrict trade volume in the app..  that really would be a good feature.   If I dont intend to trade 1 lot +..  then It would be very nice to be able to prevent that from ever executing a trade like that..  by accident.
