Does anyone else make this mistake?
Three times recently Iāve clicked without meaning to, on the invisible Buy button, in the watchlist column.

Aargh!. Of course value immediately goes negative. I exclaimed to my wife that Iād just bought Ā£25k of Natural Gas by mistake.
She blew up.
That one cost me about £30.
Two yearsā supply of Cocoa cost me 55p.
After a tense few minutes this one turned out to be fortunate, + about £120 for a very short time:

50,000 Auzzie dollars to sell to an American. āBuyā mistake.
Cost me a fiver.
I was wondering about sticking a stripe of pvc tape down the screen so I canāt click on it.
?
Are you trying to suggest your app doesnāt make you confirm the trade - as soon as you click ābuyā the trade goes through 
There is a setting for ā1 click tradingā. I assume it does what it says on the label and you can enable/disable it how you wish. Obviously if you enable itā¦
Yep. Itās the way the app came (cfd), out of the box but with position CLOSE confirmation, for some reason. The Settings box is one of those you might not realise scrolls, because thereās no bar visible until you hover over it.
(Itās like the silly lateral bar at the botton of the chart screen - you know, you go to move an Alert and hit the invisible bar and lose your displayā¦
Yes Kennybobs, itās crap design.

Even with the thing in front of me I donāt know whch characters youāre counting.
There is zero gap between the edge of the skinny tab for closing the side panel and the button, which is not clear, for doing a trade. Yes it comes up very pale grey but then itās too late.
A bad result would mean the company being taken to court, where it wouldnāt have a leg to stand on. (My wifeās a barrister covering that sort of thing).
