FSFL delays in buying shares

HI investing in FSFL in small amounts as and when i can … i have noticed that shares are not bought instantly but seem to take quite some time … I know they are not on main markets and these trades can take a little while is there a set time they pick up trades or is it pot luck any help appreciated

It happened with me not long time ago with PDL - the delay is because of Low or even very Low volume of trading. If you want to Buy = someone has to Sell and vice versa if you want to Sell = some has to Buy
