I am somewhat confused. I sifted through older threads in this and other forums on the topic of liquidity, order execution and lot size. While one might think that this should not be an issue for an beginner, there is still an observation that confuses me. With a misconception that I had about position size calculators like the one of Myfxbook out of the way, I played around with it, putting in different numbers and applying them to different currency pairs. For the following let's assume a risk ratio of 0.5% and a stop loss of 50 pips, account balance of $10.000. Applying these numbers to major pairs and the calculator gives back small lot sizes, like for example USD/JPY with the above figures 0.11 lots. However, switching to exotics like USD/HUF with an exchange rate of about 1:250 the lot size incresases dramatically to about 25 lots. While this is not the surprising part, the implication of that for me is: Some say that problems with your order getting filled can already occur with 10 lots. For this USD/HUF example that is more than twice that, so I used to wonder how you could actually put on a major trade (assuming a greater account balance than 10.000) in an exotic currency pair if already with not too big an account and a conservative risk you end up with 25 lots for USD/HUF or with 1.8 lots for USD/MXN or with 1.2 lots for USD/ZAR, also taking into account that for exotics liquidity is not as high as for majors. I have to say that I don't really have a good idea of liquidity and order filling in relation to lot size at this point, that is why I ask here. The fact that even with as little as 10.000 bucks and a conservative risk ratio you can end up with quite a few lots led me to ask this question.
