You have just discovered ask and bid, congrats.
Now press F8 and go to tab 'show'
There check 'show ask price line'
To see why it happens.
So the ask line is the spread? , In my sell trade as long as this line is bellow my entry then I am in profit , right ? Also this ask line will be the line that hits my stop loss and take me out , not the current price line , right ?
Also the spread is variable and from what is see live on the cart the spread line remains variable also one i am in a trade , I can see it getting closer and moving away from the price line as the spread gets bigger or smaller .. am i right about this ?
