Please help me with my EA

[tkuan77]

Hi guys, I am still quite new to all this EA programming. I have done up a trail EA on my own but I keep encountering some errors. My EA would only open 1 trade and after the first trade, it stops opening trade even after the conditions are met. Please advise if anyone knows what is wrong with my codes.

Criteria:
1) when SMA short crosses SMA Long upwards, only look at long trade. Open trade when LWMA short crosses LWMA long upwards.

2) when SMA short crosses SMA Long downwards, only look at short trade. Open trade when LWMA short crosses LWMA long downwards.

3) only open 1 trade at a time.

4) SL and TP = 100pips
