I’m trying to write just the letters A and S in the fields for placing orders in long (Newlong) and short (NewShort) on the Settings-Hotkeys tab, but I can’t do it, what could be the reason?

: Interface configuration

Only certain buttons or combinations of buttons can be set in the hotkey field:
a) Function keys (F1, F2, F3…)
b) Combination of SHIFT / CTRL / ALT keys + number / letter.

The hotkey cannot be set separately for a “letter” – this is done on purpose so that when typing text you do not accidentally press a single “letter” key on the keyboard and an order would be unexpectedly placed on the chart.

For hotkeys you can also use some service buttons Caps Lock, Num Lock, Del, BkSp, arrow buttons, etc. But it is strictly not recommended to set hotkeys on them, because they participate in typing and keyboard control and can also lead to unplanned triggers in the bot.
In addition, it is necessary to make sure that combinations of hotkeys do not coincide with each other, so that there is no conflict of actions in the bot.
