Trailing SL and Partial Close fix for EA

Hello,

I have an EA that I have developed with the help of ChatGPT, but it is not working quite as required. The conditions that check for entry work fine, it places orders fine with the correct stop loss and volume most of the time, although it probably needs tidying up. I am having trouble with trailing stop loss and partial close functions, they seem to be triggering inconsistently or not at all and I'm afraid I have lost faith in ChatGPT's ability to resolve the issues I'm having. The trailing stop and partial close should function as detailed below:

• Partial close: when price reaches the profit level the same in points as the stop loss distance, half the trade’s volume is closed. For example, if a buy trade opens with 1.5 lots at 1.10000 and the stop loss is at 1.09900, when price reaches 1.10100, 0.75 lots is closed, the remaining 0.75 lots are left to run.
• Trailing stop: for each 0.5* SL distance the trade moves in favour, the stop loss moves in favour by that distance. For example: a buy trade opens at 1.10000, the stop loss is at 1.09900. Price reaches 1.10050, the stop loss moves to 1.09950. When price reaches 1.10100, the stop loss moves to 1.10000 and half the volume is closed as in the point above.
• SL distance reduction: once we have closed half of the volume, every 0.5*original SL distance the stop loss moves in favour it is also reduced by one third of the CURRENT distance. This will require a bool flag that will change when the partial close is triggered. For example: a trade opens at 1.10000, the stop loss is at 1.09900. Price reaches 1.10050, the stop loss moves to 1.09950. When price reaches 1.10100, the stop loss moves to 1.1000 and half the volume is closed. Then price rises again to 1.10150, the stop loss moves first to 1.10050, then reduces by a third, in this example 100/3‎ = 33.333take this off the original SL distance and round to nearest point= 67. So the new SL is placed at 1.10088. This reduction continues for every 0.5*original SL distance the trade moves in profit. So at the next 0.5 SL interval, which is 1.10200, SL moves up to 1.10133 then reduces by another third so 67 * 0.67 = 44.89 = 45. New stop loss is 1.10200 - 45 points = 1.10155.

I will provide the current version of the code as well as full specifications for the strategy once a developer is selected.
