two sides of a trade

What is vertical trade?

example
tennis
player A   back 2.50 lay 2.60
player B    back 1.6   lay 1.7

place lay or back on two player to make a trading
instead lay then back (or back then lay) for same player.

not dutching

From what you have explained, I can see that you will lose in both cases, i.e. if you place two back bets at 1.6 and 2.5, presumably both £10, you will lose (1.6-2)*10 = -£4.

If you back at 2.5 then lay at 2.6 on the same player, or back 1.6, lay 1.7, you will get the reverse of hedging, i.e. all red instead of all green.

So what am I missing here?

it was just an example
i know to make profit i place a back above lay for a trade

but it seems make a trade cross over i don't know if it's the good term.

example
tennis
player A   back 2.50 lay 2.60
player B    back 1.6   lay 1.7

place lay or back on two player to make a trading
instead lay then back (or back then lay) for same player.

not dutching

i place  lay 10 £ @1.7 on player B i must  place lay IN BELOW 2.32 on player A to make profit exact ?

not dutching

i place  lay 10 £ @1.7 on player B i must  place lay IN BELOW 2.32 on player A to make profit exact ?

Why is it NOT Dutching then?  Seems pure lay Dutching to me, with a book% of 100/1.7 + 100/2.32 = 101.93%

with dutching i place two lays (tennis) for amount fixed

here i place  one lay  lay 10 £ @1.7 on player B then i must  place lay IN BELOW 2.42 (1/(1.7-1)+1) manualy on player A to make profit .
