Bot Zero Spread

 
I only do forex in zero spread accounts, in zero spread accounts at times the pairs can show a spread, there's how I can make a bot that makes a sell order at 70, and closes the order at 30, and which only opens the order when the spread is zero? Example, if the spread is 9, and the rsi reaches 70, the robot does not make a sell order because the spread is not zero. Can I make a bot that works like this? And how would I make this bot?

learn coding or pay for someone who can code for you

 
In fact, you cannot.

Time is against you.

You will always only know the spread of the last received tick. You cannot know if the next tick will have no spread.

And you certainly do not know if the tick which executes your order will have no spread.

You can only assume.
